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 = 2.24 L at STP
Thus, 2.24 L of the gas at STP weight = 4.4 g
`therefore 22.4` L of the gas at STP will weigh = 44 g
But 22.4 L of a gas at sTP = Molar mass of the gas
`therefore " Molar mass of the gas = 44 g"`
