What is the concentration of each of these solutions expressed as a percent sucrose by mass? a) 17g sucrose mixing in 183g water b) 30.0g sucrose mixing in 300.0g water

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

= 9.0 %


hope this helps!
