Question

MOLECULAR MASS OF NA2SO4​

Answer 1

142.066 Grams/Mole

Given:

The compound which is given to us is Na2SO4

(Sodium Sulfate)

To Find:

Molecular Mass of Na2SO4

Molar Mass of Sodium = 23

Molar mass of Sulfur = 32.066

Molar mass of Oxygen = 16

Now,

Calculating the molecular mass of Na2SO4

= 23 x 2 + 32.066 + 16 x 4

= 46 + 32.066 + 64

= 110 + 32.066

= 142.066 Grams/Mole

Therefore, the molecular mass of Na2SO4 is 142.066 Grams/Mole.
