Mass of solute  equals  100 g
Mass of solvent equals  400 g
Mass of solution = 400 + 100 = 500 g
Mass % of solution = 
$$\frac{ Mass~ of ~solution  }{  Mass ~of ~solute~×100 }$$
​$$=\frac{ 100 ~x~100 }{ 500 } = 20$$

okokok you help a lot tysm (: but the answer was 25 🤔 but even so, the formula was right, it was just a slight miscalculation as the answer

I don't see how it would be 25, I did the work again and it still adds up to do so idk

Yeah I don't get it either, my biggest problem was remembering the formula itself, if I got the answer wrong it's alr
