A solution contains 5.00 5.00 g of solute in 13.9 13.9 g of solvent. What is the mass percent of the solute in the solution?

The answer is 26.45%

Explanation:

Given:

Mass of solute = 5 g

Mass of solvent = 13.9 g

Required

Mass percent = ?

Solution

Mass percent is calculated by

Mass percent = (Mass of solute / mass of solution) x 100

Mass percent = mass of solute / (mass of solute + mass of solution) x 100

Mass percent =

Mass percent = 26.45 %

according to kinetic-molecular theory, the following would not be considered an ideal gas:

a gas at very low volumes, when gas particles are very close together

a gas at very low temperatures, when gas particles have very little kinetic energy a gas

a gas with highly polar molecules that have very strong intermolecular forces
