Answer:  156040.5Nm^{-2}

Explanation:

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = ?

V= Volume of the gas = 5dm^3 = 5 L     {tex](1dm^3=1L)[/tex]

T= Temperature of the gas = 27°C = (27+273) K = 300 K

R= Gas constant = 0.0821 atmL/K mol

n=  moles of gas= \frac{\text {given mass}{\text {Molar mass}}=\frac{10g}{32g/mol}=0.3125

Putting in the values:

P=\frac{nRT}{V}=\frac{0.3125\times 0.0821\times 300}{5}=1.54atm

1 atm = 101325Nm^{-2}

1.54atm=\frac{ 101325}{1}\times 1.54=156040.5Nm^{-2}

Thus pressure will be 156040.5Nm^{-2}
