Question

. Calculate the number of moles in 56g of H20

Answer 1

Answer:

3.11 moles

Explanation:

We are given 56 g of water (H₂O)

Required to calculate the number of moles of water.

• The relationship between moles, mass and molar mass is given by;
• Moles = Mass ÷ molar mass

in this case;

• Mass of water = 56 g
• Molar mass of water = 18.02 g/mol

Therefore;

Moles of water = 56 g ÷ 18.02 g/mol

                         = 3.11 moles

Therefore, moles of water in 56 g will be 3.11 moles
