Question

If 3g of carbon reacts with 8g of oxygen to give 11g of carbondioxide, calculate the mass of carbon and oxygen required to prepare 44g of carbon dioxide​

Answer 1

Answer:

Correct option is

C

11 g

This is governed by the law of definite proportion. Carbon and oxygen combine in 3:8 ratio. So 11 g of carbon dioxide is formed. 

Hence, in the latter case too, only 8 g of O2 will be reacted with 3g of carbon (because carbon is the limiting reagent here ) to form 11g of CO2 and  42 g of oxygen will remain unreacted.

Hence, the correct option is C.
