Answer:2:1

Step-by-step explanation:As ratio of hydogen and oxygen is 2:1

Answer:the ratio in the no.of atom is 2:1

Step-by-step explanation:as the mass ratio is given as 1:8

now dividing it by its molar mass

molar mass of H2=2

molar mass of O2=32

mole ratio is 1/2 : 8/32

=2:1

mole x avagadro number is no.of atom:

so 2 x 6.022 x 10^23 : 6.022 x 10^23

by cancelling 6.022 x 10^23 both sides

We get 2:1 ratio for the no.of atoms
