Question

B) Write down the molecular formulae 1) Sulphuric acid .. ... 2)Methane.. ... ..​

Answer 1

Answer:

The molecular formula of SULPHURIC ACID IS H2SO4.

Molecular formula is CH4

Answer 2

Answer:

1) The molar mass of hydrogen is 1

Molar mass of sulphur (S) is 32

Molar mass of oxygen (O) is 16

Now ,

2(1)+32+4(16) = 98

Molar mass of sulphuric acid i.e. H2SO4 is 98.

2) For methane:

Molecular formula is CH4

For ethane:

Molecular formula is C2H6
