Question

Medal
0.976 mol sample of hydrogen gas at a temperature of 9.00 °C is found to occupy a volume of 27.4 liters. The pressure of this gas sample is
? mm Hg.

Answer 1

Use the ideal gas law equation: PV=nRT
P is the pressure in mmHg, convert this to atm
V is the volume in liters
T is the temperature in kelvins
n is the moles
R is the constant which is 0.0821 L*atm/mol*K

Answer 2

\[PV=nRT\]
You are solving for pressure in this case, so divide v to both sides to isolate p(pressure)
\[\frac{ PV }{ V }=\frac{ nRT }{ V}\]
\[P=\frac{ nRT }{ V } \]
