mass percent: ___________

 

A solution contains 3.40 g of solute in 12.4 g of solvent. What is the mass percent of the solute in the solution?

A solution contains 3.50 g of solute in 13.3 g of solvent. What is the mass percent of the solute in the solution?

can you please explain how to figure this out: I am so lost on how to figure out the numbers and percentages. I know the formula not sure how to place it.

1. How many grams of solvent are in a 14 % NaCl solution?
______ g of solvent

2.

What is the mass percent of a solution that contains 7 g of sugar dissolved in 63 g of solvent?
(__________ m/m %)

3.

The percent sugar of a solution that contains 7 g of sugar dissolved in 63 g of solvent is 10%. In this case the mass of solute is 7 g and the mass of solution is 7g + 63g = 70g.

The total mass of this solution is ___ g.

4. What is the mass percent of a solution that contains 18 g of salt dissolved in 72 g of solvent?
________ m/m %
