Question

Calculate the relative molecular mass of sulphuric acid (H₂SO₄) . Given At. wt. of hydrogen =1; At. wt. of sulphur= 32; At wt. of oxygen =16 ​

Answer 1

Answer:

given ,

weights of

hydrogen: 1

sulpher: 32

oxygen: 16

Explanation:

here it is clear that there are two molecules of hydrogen

symbol of hydrogen: H

therefore ; atomic weight * number of atoms : 1*2= 2 gm ( you can take unit as gm or u)

now let's take sulphur molecules;

symbol of sulphur: S

weight : 32

number of atoms = 1

therefore : 32*1= 32 gm

now let's take oxygen molecules:

symbol :O

weight : 16

number of atoms given : 4

therefore: 16*4= 64 gm

so here's the final answer;

add all molecule weight : 2+32+64

= 98 gm
