Question

Carbon and oxygen combine ni ratio 3:8by mass to form a gas Y what mass of carbon would be required to react completely with 40g of oxygen gas

Answer 1

Hello Mate!

So, carbon (C) and oxygen (O) combine at ratio of 3:8. So, if 40 g of oxygen is given then,

Taking carbon weight as X

3:8 = X:40

3/8 = X/40

3/8 × 40 g = X

3 × 5 g = X

15 g = X

Hence, 15 g of oxygen will react with 40 g of oxygen completely to form Y gas.

Have great future ahead!
