Question

The ratio of moles of atom in 12g of magnesium and 16g of sulphur will be

Answer 1

Molar mass of magnesium = 24g

Given mass of magnesium = 12g

Number of moles = given mass of the element/ atomic weight of element

Number of moles of magnesium = 12/24 = 0.5 moles

Molar mass of sulphur = 32g

Given mass of sulphur = 16g

Number of moles = given mass of the element/ atomic weight of element

Number of moles of sulphur = 16/32 = 0.5 moles

Hence, 12 g of magnesium and 16 g of sulphur represents a mole ratio of 1 : 1

Answer 2

Answer:

State as 12g magnesium and 12g sulfur mole
