Question

carbon and oxygen react in ratio of 3:8 by mass to form CO2.what weight of carbon should be used to react completely with 32g of oxygen

Answer 1

Crabon and oxygen combine together to form co2

The ratio of their combination is 3:8

Now,
Let the mass be x
So,
The ratio of combination will be 3x : 8x

Now,

Mass of oxygen is given as 32 grams

So,
8x = 32
Or,
x = 32/8 = 4 grams

So,
The mass of carbon to react with 32 grams of oxygen is 3x
So,
3x = 3*4
Or,
3x = 12 grams


Therefore, 12 grams of carbon will react completely with 32 gram of oxygen.
