How many moles are there in 5.80 X 1024 molecules of sodium sulfate, Na2SO3?

Explanation:

To convert from molecules to moles, Avogadro's Number: 6.02*10²³ must be used. This number is the amount of particles (molecules, atoms, etc.) in 1 mole of a substance. In this case, the particles are molecules of sodium sulfate. Let's create a proportion.

Multiply by the given number of molecules.

Flip the fraction so the molecules of sodium sulfate cancel.

Divide.

The original measurement has 3 significant figures (5, 8, and 0), so our answer must have the same.

For the number we calculated that is the hundredth place. The 1 in the thousandth place tells us to leave the 3.

There are about 9.63 moles of sodium sulfate

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
