Question

Calculate the mass percent 250g of salt solution that has 3.50g salt residue

Answer 1

1.4% salt residue

Step-by-step explanation:

Mass percent can be found using the formula:

mass of solute (grams)
------------------------------------ x 100%
mass of solution (grams)

Therefore, since you have been given the weights of both the solute and solution, you can use the formula to solve for the mass percent.

3.50 g salt residue
----------------------------- = 0.014 x 100% = 1.4% salt residue
250 g salt solution
