The volume of Sulfur dioxide gas that would be collected at 237c and 10.7 atm is
0.446 L

it is calculated using ideal gas equation
that is PV =nRT
P(pressure)= 10.7 atm
V(volume=?
n= number of moles = 18.2 g/159 =0.114 moles

by making V the subject of the formula V= nRT/P

(0.114 mol x0.082 L.atm/mol/k x510 K)/ 10.7 atm = 0.446 L
