Answer:

There are 4 non bonded electron pair in tetracyanoethylene

Explanation:

In tetracyanoethylene, four cyano groups are attached with an ethylene moiety.
Non bonded electron pairs in tetracyanoethylene molecule are present on N atoms in cyano groups.
Each N atom in a cyano group contains one non bonded electron pair.
There are 4 cyano groups in tetracyanoethylene.
Hence there are 4 non bonded electron pair in tetracyanoethylene.
Lewis structure of tetracyanoethylene has been given below.

NeX [460]

Answer: The molar mass of the gas is 31.6 g/mol

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 3.0 atm

V = Volume of gas = 25.0 L

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $27.0^0C=(27.0+273)K=300K$

$n=\frac{PV}{RT}$

$n=\frac{3.0atm\times 25.0L}{0.0821 L atm/K mol\times 300K}=3.04moles$

Moles = $\frac{\text {given mass}}{\text {Molar mass}}$

$3.04=\frac{96.0g}{\text {Molar mass}}$

${\text {Molar mass}}=31.6g/mol$

The molar mass of the gas is 31.6 g/mol
