Question

32 ml of CO2 is obtained when x g of carbon is burnt to form co2​

Answer 1

Answer:

Solution:

Total molecular weight of CO

2

= molecular weight of carbon + molecular weight of dioxygen.

= 12g+32g=44g

1 mole of carbon(6g) and 1 mole of dioxygen (32 g ) produce 44 g of carbon dioxide CO

2

Then 1 mole of carbon burnt with 16 g of oxygen , it will produce 44× 16 /32 = 22 g of CO

2

so when 2 mole of carbon burnt with 16 g of oxygen , it will produce 22×2 g of CO

2

i.e 44g of CO

2

will be generated.

Hence, 22×2=44g is the answer.
