The volume occupied by `7.40 g of CO_(2)` (at `STP`) is

A

`3.8 L`

B

`4.5 L`

C

`5.6 L`

D

`2.9 L`

Text Solution

Verified by Experts

The correct Answer is:
A

Since `1 mol` of an ideal gas occupies `22.4 L at STP`, we have
`V_(CO_(2)) = (n_(CO_(2))) (22.4 (L)/(mol))`
`= ((7.40 g)/(44 g mol^(-1))) (22.4 L mol^(-1))`
`= 3.76 L`
