236 I DONT KNOW I AM TOTALLY THAT IS NOT THE ANSWER
A) mass of solute = 17 g
mass of solvent = 183 g
% = mass of solute / total x 100
% = 17 / ( 17 + 183 ) x 100
% = ( 17 / 200 ) x 100
% = 0.085 x 100
= 8.5 %
________________________________
b) mass of solute = 30.0 g
mass of solvent =300.0 g
% = mass of solute / total x 100
% = 30.0 / ( 30.0 + 300.0 ) x 100
% = (30.0 / 330.0 ) x 100
% = 0.090 x 100
<span>= 9.0 %

hope this helps!
