Answer 2

Answer:

1 the molecular mass of water is: relative mass of hydrogen=1u relative mass of oxygen-16u .. (2 x Atomic mass of hydrogen) + (1x

Atomic mass of oxygen)

[2(1.0084)+1(16.00 u)]

→ 2.016 u + 16.00 u

⇒18.016

→ 18.02 u

2 molecular mass of hno3 is: hydrogen=1u oxygen=16u

nitrogen=14u

..(1 x Atomic mass of hydrogen) + (1

x Atomic mass of oxygen)+(3 x Atomic mass of oxygen)

1+14+48

=63g/mol
