What is the percent by volume of isopropyl alcohol in a solution that contains 24 mL of isopropyl alcohol in 1.1 L of water?
this the other one i need help with and thanks for the last help

%$ by volume means (mL solute/100 mL solution)*100
Assuming the volume of isopropyl alcohol and water are additive, then
(24/(1,100 + 24)*100 =
