Question

calculate the mass of each element in Na2So4​

Answer 1

Answer:

Given Element: Na2SO4.

Calculating the Molar Mass Of Na2SO4: = [(2 x 23.0) + (32.066) + 4(16.00)]

Formula Used To Find The Mass Percent Of An Element:

Calculating Mass Percent Of The Sodium Element:.

Mass Percent Of The Sulphur Element:

Mass Percent Of The Oxygen Element:

Answer 2

Answer:

The molecular formula of sodium sulphate is (Na2SO4).

Molar mass = atomic mass of Na(23) + atomic mass of S(32.066) + atomic mass of O(16)

Molar mass of (Na2SO4) = [(2 × 23.0) + (32.066) + 4 (16.00)] = 142.066
