Let’s say 26*10^-3 mg of rilboflavin are in the 25.0ml of sample milk if it’s needed.
One cup = 90.7g
8. The recommended daily allowance (RDA) of riboflavin is 1.3 mg/day for adult males and 1.1 mg/day for adult females. Let’s take the a on your measurement, what percentage of the RDA does 1 cup of the dried milk provide? verage and consider the RDA to be 1.2 mg/day. Based

Answer
Density of powdered milk is 0.449 gm/ ml
25 ml powdered milk weighs 25× 0.449 grams = 11.225 grams
11.225 grams milk powder contains 26×10^-3 mg riboflavin
90.7 grams milk powder contains (26×10^-3×90.7)/11.225 mg = 0.21 mg riboflavin
So, one cup milk provides (0.21×100)/1.2 % = 17.5% riboflavin per day.
