Question

calculate the molar mass of sodium sulphate Na2SO4 ? i will mark you as brainleast and give you thanks if you give me the correct answer !!!​

Answer 1

Answer:

Sodium Sulphate = Na2SO4

Atomic mass of Na = 23 u

Atomic mass of S = 32 u

Atomic mass of O = 16 u

Molecular mass of Sodium Sulphate is

Na2So4 = 2×23 + 32 + 4×16 = 46 + 32 + 64 = 142 kg/mol

Hope this answer helps you out.

Answer 2

Answer:

142 u is the correct answer
