The ideal gas equation is expressed as,
PV = nRT
where P is the pressure,
V is the volume,
n is the number of moles,
R is the universal gas constant, and
T is temperature
From this, we get the expression for V.
V = nRT/P
Substituting the known values,
V = (1 mol)(0.0821 L.atm/mol K)(100 C + 273.15) / 10 atm
V = 3 L
ANSWER: 3L
