Question

Calculate the following quantities.
(a) the pressure, in Torr, of 20.7 mol of an ideal gas in a volume of 175 mL at 19.0°C
__________ Torr
(b) the volume, in milliliters, of 46.0 mg H2(g) at 1.45 atm and -40.°C
__________ mL
(c) the mass, in kilograms, of 603 m3 of O2(g) at 709 Torr and 8.00°C
___________ kg
(d) the pressure, in pounds per square inch (psi), of 110 mg Ar(gas) in a 225 mL flask at 43°C
____________ psi

Answer 1

You can solve all of them with the ideal gas law

PV = nRT

Don't forget to convert temp. to Kelvin.

For pressure, 1 atm. = 760 torr = 14.7 psi.
