Question

Calculate the molar mass of the following:
(1) H20 (ü) CO, (iii) CH,​

Answer 1

Answer:

Explanation: One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

Answer 2

Answer:

(1) 18

(2) 28

(3) 13

Explanation:

(1)  (1 x 2 ) + 16 = 18

(2) 12 + 16 = 28

(3) 12 + 1 = 13
