The molarity of a solution of CaCl2 is calculated as below

convert  mm  to g
1mg =0.001 g
33500 x 0.001 =33.5 g
find the  moles of CaCl2 = mass/molar mass

=33.5 g/ 111 g/mol =0.3018 moles

molarity =moles/volume

=0.3018/0.352 =0.857 M

Question
The chart shows the solubility of different substances. Which statement is represented by the graph? Temperature can change the solubility of a solute. Temperature has no affect on the solubility of a solute. Salt has a greater solubility than sugar. Nitrite salt has a greater solubility than sugar.
Solution 1
Answer: 1) Temperature can change the solubility of a solute.

Explanation:

The chart is missing so there is no way to tell what does the graph show.

Yet, I can help you because I can explain the status of each statement of the choices. As you will see there is only one possibility..

1) Temperature can change the solubility of a solute.

Yes, temperature definetly can, and mostly do, modify the solubility of a solute.

You can search any chart of solubility and will find that.

I can give you two examples:

a) Sodium chloride: dissolve some spoons of salt in a cold water  until you can not dissolve more. Then, heat the water, you will find that more salt will get dissolved, proving that the temperature of the solution increases the solubility of sodium chloride.

b) Carbon dioxide gas: the soft drinks have CO₂ molecules dissolved in it.

The higher the temperature of the soft drink the less the amount of CO₂(g) that can be dissolved. That is why the soda bottling plants cool the beverage before adding the CO₂(g).

2)
Temperature has no affect on the solubility of a solute.

Since this is the opposite to the first statement and the first is true, this is false.

3) Salt has a greater solubility than sugar.

False.

This is an empirical result, which you cannot predict theoretically. So you need to see at the data either in a table or in a chart. Else you can test it at home. After the empirical data are shown it results that more grams of sugar can be dissolved in water compared to salt.

That is something you ca see in a chart or you can prove by yourself.

4) Nitrite salt has a greater solubility than sugar.

False.

Looking at some data you can find that sodium nitrite solutiliby is aroun  70 - 100 g/10 g while sugar (sucrose) solutiblity is around 180 - 235 g/ 100 g.

Solution 2

Question
Calculate the pH of 100.0 mL of a 0.150M aqueous solution of HNO3
Solution 1
PH scale is used to determine how acidic, neutral or basic a solution is.
pH can be calculated using the following equation
pH = -log[H⁺]
HNO₃ is a strong acid therefore completely dissociates into its ions as follows
HNO₃ --> H⁺ + NO₃⁻
1 mol of HNO₃ dissociates to produce 1 mol of H⁺ ions
Therefore [HNO₃] = [H⁺]
[H⁺] = 0.150 M
since concentration has been given, its not necessary to consider the volume as concentration is constant throughout the whole solution
pH = -log(0.150 M)
pH = 0.82
the pH of solution is 0.82
Question
What change would occur in the kinetic energy of vapor if a container of vapor is placed at 0 Kelvin?
Solution 1

The kinetic energy would be practically equal to zero

Explanation:

Temperature is a measure of the kinetic energy of the molecules in a system, that is to say that if the temperature increases so will do the kinetic energy and the molecules will move faster.

Absolute zero or 0 Kelvin is the lowest possible theoretical temperature. At this temperature the energy level of the system is as low as possible, so that the particles, according to classical mechanics, lack movement; however, according to quantum mechanics, absolute zero must have a residual energy.

Solution 2
Partical will have no kinetic energy

Question
You are given the percent by mass of the elements in a compound and wish to determine the empirical formula. Label each of the following statements as true or false and explain your answers. a. You must assume exactly 100.0 g of the compound. b. You must convert percent by mass to relative numbers of atoms. c. You must divide all of the percent by mass numbers by the smallest percent by mass. d. You cannot solve for the emp
Solution 1
A) False, you can use any basis, 1 g, 100 g, 100 kg, or any other value. The relative proportions will remain the same.
b) True, since an empirical formula is defined by the number of atoms of each element, it is this number of atoms, rather than atomic mass, that is needed.
c) False, you would have to divide the numbers of atoms by the smallest number of atoms. (not the mass %s)
d) False, it is possible given the % by mass.
Question
What kinds of features would you expect to see at the edges of two plates, like these that are moving apart at their boundary?
Solution 1
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Hope this helps! :D

Question
The molecular weight of H2 and the mass of 1 mole of H2 are _____. a.quantities b.different quantities c.inversely related d.not the same
Solution 1

Explanation: According to avogadro's law, 1 mole of every substance contains avogadro's number of particles.

Molecular weight of = 2.0 g/mol

To calculate the moles, we use the equation:  Now 1 mole of molecule contains = of molecules.

Thus both represent same quantities.

Solution 2
The molecular weight of H2 and the mass of 1 mole of H2 are quantaties. The mass of 1 mole of H2 is 2.01588g while the molecular weight of H2 is also 2.01599g. This means they are both the same amount of H2.
