Amixture is made by combining 1.62 lb of salt and 5.20 lb of water.
what is the percentage of salt (by mass) in this mixture?

oof idk I would suggest looking at an example and try going off that

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
