A- The recommended daily allowance (RDA) for trace amounts of magnesium is 410 mg/day for men. Express this amount in Ī¼g/day. B- For adults, the RDA of lysine amino acid is 12 mg per kg of body weight. How many grams per day should a 75 kg adult receive? C- A typical multivitamin tablet can contain 2.0 mg of vitamin B2 (riboflavin), and the recommended daily dose is 0.0030 g/day. How many tablets of this type should a person take each day to obtain the adequate amount of this vitamin, assuming they are not getting any from other sources? D- The trace element selenium is 0.000070 g/day. Express this dose as mg/day.

(a) The recommended daily allowance (RDA) of the trace metal magnesium is 410 $\mathrm{mg} / \mathrm{day}$ for males. Express this quantity in $\mu \mathrm{g} / \mathrm{day} .$ (b) For adults, the RDA of the amino acid lysine is 12 $\mathrm{mg}$ per kg of body weight. How many grams per day should a 75 $\mathrm{kg}$ adult receive? (c) A typical multivitamin tablet can contain 2.0 $\mathrm{mg}$ of vitamin $\mathrm{B}_{2}$ (riboflavin), and the RDA is 0.0030 $\mathrm{g} / \mathrm{day} .$ How many such tablets should a person take each day to get the proper amount of this vitamin, assuming that he gets none from any other sources? (d) The RDA for the trace element selenium is 0.000070 $\mathrm{g} /$ day. Express this dose in mg/day.
