Answer 1

Hey mate,.

(i)C2H5OH = 2×12+5×1+16+1

=>>46 amu.

(ii)H2SO4=2×1+32+4×16

=>>98 amu.

Hope it will help you

Answer 2

ANSWER :-

MOLECULAR MASS :-

JUST add the individual mass of the elements or atom present in the molecule.

c2н5oн = 12*2 + 5(1) + 16 + 1 = 46 aмυ/gм

н2ѕo4 = 2(1) + 32 + 16*4 = 98 aмυ/gм
