Mass % of a compound can be shown as:
Mass % = (mass of solute / mass of solution) * 100
10% by mass urea of 100 g indicates = (100 * 10) / 100 = 10 g
Mass of glucose = 200 g
Mass % glucose = [mass of glucose / (mass of glucose + mass urea) ]* 100
= [200 / (200 + 10) ] * 100 = 95.21 %
Hence, mass percent of glucose is 95.21 %
