Question

The molecular weight of nacl is 58 how many mg is 50 umolof nacl

Answer 1

Explanation:

mol of NaCl is 58 g, so 1 µmol is 58 µg, so 50 µmol is 2,900 µg = 2.9 mg. 1% (w/v) contains 1 g in 100 ml and, therefore, 10 g in 1 litre. A 1 M solution of glucose contains 180 g/l, so 10 g/l represents a molarity of 10/180 = 0.056 M (or 56 mM).

Answer 2

Explanation:

mol of NaCl is 58 g, so 1 µmol is 58 µg, so 50 µmol is 2,900 µg = 2.9 mg. 1% (w/v) contains 1 g in 100 ml and, therefore, 10 g in 1 litre. A 1 M solution of glucose contains 180 g/l, so 10 g/l represents a molarity of 10/180 = 0.056 M (or 56 mM
