How many grams are in 2.3 x 10^-4 moles of Ca3(PO4)2

Answers

Answer 1

Answer: Molar mass

Ca₃(PO₄)₂ = 310 g/mol

1 mole -------------------> 310 g
2.3x10⁻⁴ mole ---------> ?

m = 2.3x10⁻⁴ * 310 / 1

m = 0.0713 g

hope this helps!

As the temperature of a liquid increases, its vapor pressure(1) decreases
(2) increases
(3) remains the same

Answers

As the temperature of liquid increases, its vapor pressure increases. Therefore, option (2) is correct.

What is vapour pressure?

Vapour pressure can be defined as the pressure exerted by a vapor with its condensed phases in a closed system at a given temperature. The equilibrium vapor pressure is also served as an indicator of the rate of evaporation of a liquid.

A material that has a high vapor pressure at normal temperatures is commonly referred to as a volatile material. The pressure exhibited by the molecules of the gas above a liquid surface is called vapor pressure.

The temperature and the vapor pressure of liquid are directly related to each other. If the temperature of the liquid increases, more gasmolecules have the energy to escape from the surface of the liquid.

Therefore, the vapor pressure increases with an increase in the temperature of the liquid.

Which compound is an electrolyte?
(1) C6H12O6 (3) CaCl2
(2) CH3OH (4) CCl4

Answers

I think the correct answer is option 3. CaCl2 is the compound that is an electrolyte when dissolved in water. An electrolyte is a substance that conducts electricity in solution. Calcium Chloride when in solution dissociates into ions which allows the flow of current in the solution.

How to calculate molar mass

Answers

Molar masses of chemical compounds are equal to the sums of the molar masses of all the atoms in one molecule of that compound. After that, If you have a subscript in a chemical formula, then you multiply the number of atoms of anything next to that subscript by the number of the subscript. I'm kinda new to this stuff. Hopefully I helped :/

Molar mass is the sum of all atomic masses in a given compound in relative grams. To explain how to calculate the Molar mass, let me show you an example.

Calculate the Molar mass of H2O

now, atomic mass of H - 1
Atomic mass of O - 16

Now, molar mass = 1(2) + 16

= 2 +16
= 18 u = 18 grams (relative mass in grams)
