Expert Answer:

Mass of H2O should be 0.0819 g
Suppose vitamin is X.

percent sign space of space Carbon equals fraction numerator 0.0818 over denominator 0.2000 end fraction cross times 100 equals 40.9 percent sign

percent sign space of space hydrogen equals fraction numerator 0.0091 over denominator 0.200 end fraction cross times 100 equals 4.55 percent sign

percent sign space of space straight O equals 100 minus left parenthesis 40.9 plus 4.55 right parenthesis
