Under what pressure will a scientist need to store 0.400 moles of gas if the container has a volume of 200.0 mL and the temperature is kept at 23.0 C?

Verified Answer :

Answer: 48.60 atm

Explanation: Using ideal gas equation:

\(PV=nRT\)

\(P=\frac{nRT}{V}\)

P= pressure = ? atm

V= volume =\(200ml=0.2L\)  

n = no of moles = 0.400

R= gas constant =0.0821 Latm/molK

T = Temperature \(=23^0C=(23+273)K=296K\)

\(P=\frac{0.400\times 0.0821\times 296K}{0.2L}=48.60atm\)
