What is the mass of Oxygen will be present with 6 gram of carbon in co2

Answer»

Original ratio of CABON and oxygen mass in co2 = 12 : 32
NEW, ratio a/c to question = 6 : X ,
where, x = new mass of oxygen
Since we know that,
Ratio of mass of two elements in a compound always remains same .
So , on comparing,
12/32 = 6/x
3/8 = 6/x
3/8×6 = 1/x
1/16 = 1/x
16 = x
So, x = 16 u
