Question

Calculate the molecular

mass of sulphuric acid (H2SO4) (atomic mass of H=1u; S=32u; O=16u)​

Answer 1

Answer:

98u

Explanation:

H2SO4

2×1+1×32+4×16

2+32+64

98u

Answer 2

Answer:

Molecular Mass of H2SO4 is 100u

Explanation:

Molecular Mass - The mass of a molecule is measured in daltons and is called molecular mass. Because they contain various isotopes of an element, different molecules of the same substance may have different molecular weights.

Given:

Atomic Mass for H, S and O as 1u, 32u, 16u respectively

$H_{2}SO_{4}$ = 2 ( H ) + S + 4 ( O )

           =  2 ( 1 ) + 32 + 4 ( 16 )

           =  2 + 32 + 64

           =  100 u

Therefore the molecular mass of H2SO4 is 100u.
