Calculate the amount of Carbondioxide that could be produced when
i) 1 mole of carbon is burnt in air
ii) 1 mole of carbon is burnt in 16 g of dioxygen
iii) 2 moles of carbon are burnt in 16 g of dioxygen.

Explanation

(i) `underset(1 " mol.")(C+O_(2))tounderset(44g)underset(1" mole")(CO_(2))`
`therefore` 1 mole of carbon when burnt in air produces 44 g of `CO_(2)`
(ii) `underset(12)(C)+underset(32)(O_(2))tounderset(44)(CO_(2))`
For burning 12g (1 mole) of carbon 32 gm of dioxygen is required. Since 16 g of dioxygen is present only 6 gm (half mole) of carbon burn producing half mole of `CO_(2)`.
Thus 22 g of `CO_(2)` is formed.
(iii) Here also 22 g of `CO_(2)` is formed since there is only 16 g of oxygen.
