The mass of `2.24xx10^(-3)m^(3)` of a gas is 4.4 g at 273.15 K and 101.325 Kpa pressure. The gas may be

Options

A. `NO`
B. `NO_(2)`
C. `C_(3)H_(8)`
D. `NH_(3)`

Answer

C

Explanation

`2.24xx10^(-3)m^(3)` of a gas = 2.24L at STP
`:. 2.24L` of a gas at STP weigh = 4.4
`:.` 22.4 L of a gas at STP weigh =44g
now 22.4 L of a gas at STP at = molar mass of the gas
`:.` molar mass of the gas = 44 g
molar mass of `C_(3)H_(8)=36+8=44g`
