Question

Calculate the relative molecular mass of ammonium sulphate (NH4) 2SO4. Given : relative atomic masses of: N=14, H=1, S=32, O=16​

Answer 1

Answer:

132

Explanation:

2(14+4)+32+64

2×18+32+64

36 + 32 + 64 = 132

Answer 2

Given - Compound ammonium sulfate

Find - Relative molecular mass of ammonium sulfate

Solution - Relative molecular mass of a compound is calculated by the formula= mass of one molecule/1/12th mass of Carbon atom.

Since 1/12th mass of Carbon atom will be 1, we can calculate RMM by calculating mass of one molecule.

One molecule weigh = (14 + 4)*2 + 32 + 16*4

RMM = 36 + 32 + 64

RMM = 132

Hence, relative molecular mass of ammonium sulfate is 132.
