How many moles of methane are required to produce 22 g of `CO_2` (after combustion?

A

0.5 mol

B

1 mol

C

0.25 mol

D

1.5 mol

Text Solution

Verified by Experts

The correct Answer is:
A
According to the chemical equation,
` CH_(4 (g)) + 2O_(2 (g)) to CO_(2 (g)) + 2H_2 O_((g))`
`44 `g ` CO_(2 (g) ` is obtained from `16 g CH_(4 (g))`
` :. ` 1 mole `CO_(2(g))` is obtained from 1 mole of `CH_(4 (g))`
hence , 22 g or 0.5 mol ` CO_(2(g))` would be obtained from 0.5 mol `CH_(4(g))` or 0.5 mol of `CH_(4 (g))` would be required to produce 22 g `CO_(2(g))`
