Question

Calculate the molecular mass of the following:
A. H20
B. Hcl
C. H2s

Answer 1

Explanation:

molar mass of h2o is 18.01528g/mol

hcl is36.46g/mol

h2s is 34.1g/mol

Answer 2

Answer:

a.H2O:2×atomic mass of H +atomic mass of O

2×1+16=18u

b.Hcl:1 × atomic mass of H + atomic mass of cl

1×1+35.5=36.5u

c.H2S: 2× atomic mass of H+ atomic mass of S

2× 1 +32=34u
