Question

Calculate the molecular mass of a) CH3COOH b) H2SO4​

Answer 1

Answer:

Acetic acid is 60.048g/mol

H2SO4 is 98g/mol

Answer 2

Answer:

a) CH3COOH <=> C2H4O2:

Molecular mass = 2(C) + 4(H) + 2(O)

= 2(12) + 4(1) + 2(16)

= 24 + 4 + 32

= 60u

b) H2SO4:

Molecular mass = 1(H) + 2(S) + 4(O)

= 2(1) + 1(32) + 4(16)

= 1 + 32 + 64

= 97u
