Question

2.8 g of an unknown gas occupied 2.24 L of volume under STP
Condition the gas may be--------
a) CO2 b) CO c) O2
d) SO2​

Answer 1

Answer:

Number of moles =

22.4

2.24

=

10

1

or, Number of moles =

Mw

4.4

=

10

1

Therefore, Molecular weight = 44 g.

Gas may be N

2

OandCO

2

as they both have molar mass of 44 g.
