Question

how many grams of sugar would be needed to give a 50.00 mL solution of FD&C Red Dye a concentration of 6.0% sugar?

Answer 1

Is this % w/w or % w/v? I'll assume % w/v
% w/v = (grams solute/50 mL)*100
Solve for grams.

Answer 2

I'm going to assume that this is mass/volume percent:

m/v%=(g/mL)*100

6.0%=(x g/50mL)*100

(6.0/100)*50=x g

Solve for x g


Which should be 3g, I believe.
