Question

Find molecular mass of CH4,H2O

Answer 1

hey!!

here is your answer... =>

=>>{ }

first let's, find out all the masses of the atoms.

carbon mass is 12

hydrogen mass is 1

oxygen is 16

now to find the total mass of methane , (CH4)

12 + (4*1)

12 + 4

= 16 amu

H2O would be

(1*2) + 16

2+16

= 18 Amu

hope this helps!
