Question

Adam drinks an 8oz glass of milk every morning. in doing so, Adam takes in 25.0% of vitamins D. if there are 29mL in every ounce of milk, how many grams of vitamin d will Adam drink in the average month

Answer 1

Volume of milk each day: 29 x 8 = 232 ml
Milk density = 1.035 g/ml
Mass of milk each day: 232 x 1.035 = 240 g
100 g of milk contains 0.025 mcg of vitamin D
Day intake of vitamin D: 240 x 0.025 x 0.25 = 1.5 mcg
Mass of vitamin D per month: 1.5 x 31 = 46.5 mcg
