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?

Respuesta :

Answer: 48.60 atm

Explanation: Using ideal gas equation:

[tex]PV=nRT[/tex]

[tex]P=\frac{nRT}{V}[/tex]

P= pressure = ? atm

V= volume =[tex]200ml=0.2L[/tex]  

n = no of moles = 0.400

R= gas constant =0.0821 Latm/molK

T = Temperature [tex]=23^0C=(23+273)K=296K[/tex]

[tex]P=\frac{0.400\times 0.0821\times 296K}{0.2L}=48.60atm[/tex]
