Answer:
the no of atoms of carbon is obtained by dividing the its % by its atomic mass.
Similar thing is done for H
but to get a comparison between the no H and C atoms the H % is divided by no of atoms of C. that gives near about 2.5
2 is multiplied to reach to the nearest whole number as composition of elements can't be in decimal
