What is the M, of C3H, COONa? A: Na = 23; C = 12, 0 = 16:
110
87
98
103

Molecular mass of is 82 g

Explanation:

Molecular mass (M) is defined as the mass in grams of 1 mole of a substance.

S.I Unit of Molar mass is gram per mole and it is represented as g/mol.

Atomic Mass of Carbon (C) = 12 g

Atomic Mass of hydrogen (H) = 1 g

Atomic Mass of oxygen (O) = 16 g

Atomic Mass of sodium (Na) = 23 g

Molecular mass of = 12(1)+1(3)+12(1)+16(2)+23(1) = 82 g
