354.5 g of chlorine gas is held with a fixed volume of 70.0 L. What is the pressure of the gas in atmospheres if it’s temperatur
zaharov [31]

Answer: The pressure of the gas in atmospheres is 1.76

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = ?

V = Volume of gas = 70.0 L

n = number of moles = \frac{\text {given mass}}{\text {Molar mass}}=\frac{354.5g}{71g/mol}=5moles

R = gas constant =0.0821Latm/Kmol

T =temperature =30.0^0C=(30.0+273)K=300.0K

P=\frac{nRT}{V}

P=\frac{5\times 0.0821Latm/K mol\times 300K}{70.0L}=1.76

Thus the pressure of the gas in atmospheres is 1.76
