Find the formula of an oxide of carbon in which the ratio by mass of oxygen to carbon is 2.00:1.00. [Solved]

C2O3

if the mass ratio of C : O is 1 : 2
Then this means that for every 1 g of C there are 2 g of O

0.0833 / 0.0833 : 0.125 / 0.0833
= 1 : 1.5

moles C = 1 g / 12 g/mol = 0.0833 mol
moles O = mass / molar mass = 2 g / 16 g/mol = 0.125 mol

mole ratio of C : O
= 0.0833 : 0.125

C2O3

0.0833 / 0.0833 : 0.125 / 0.0833
= 1 : 1.5

2 x (1 : 1.5)
= 2 : 3

2 x (1 : 1.5)
= 2 : 3

0.0833 / 0.0833 : 0.125 / 0.0833
= 1 : 1.5
