Question

calculate the molecular mass of sulphur trioxide

Answer 1

Mass = 32 +16×3 =80 g

Answer 2

Hello !!

Here is your answer !

____________________

The molecular formula is SO3.

The molecular mass :

S = 32.00 u
O = 16.00 u

1 x S = 32.00 u
3 x O = 48.00 u

SO3 = 32.00 + 48.00 = 80.00u ( Ans)
