a) 8
b) 10
c) 18
d) 20​

Answer 1

Answer:

18

Explanation:

Molar mass of water is 18

Answer 2

Answer:

c

Explanation:

One mole of

H

2

O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom.

Mass of 1 mole of Hydrogen atoms= 1 g /mol

Mass of 1mole of Oxygen atoms = 16 g/mol

Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2

Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
