The mass of 11.2 L of ammonia gas at STP is

A

`8.5` g

B

85 g

C

17 g

D

`4.25` g

Text Solution

Verified by Experts

The correct Answer is:
A
Molar mass of `NH_(3) = 14 + 3 xx 1 = 17 g mol^(-1)`
`therefore` Mass of `22. 4 ` L of `NH_(3)` at STP = 17 g
`therefore` Mass of `11.2 ` L of ` NH_(3) ` at STP = `8.5` g
