This question requires one response per row

Answer 1

We use the formula, Volume percent = Volume of solute / Volume of solution × 100 %

From given, we have the parameters, 

The volume of solute is 90 mL

The volume of solution is 3000 mL

Substitute the values in the given formula,

Volume percent = Volume of solute / Volume of solution × 100 %

= 90 mL / 3000mL × 100 %

∴ The volume percent = 3 %
