A scuba diver's tank contains 0.250kg of O2 compressed into a volume of 3.10L. What volume (in liters) would this oxygen occupy at 27 degrees Celsius and 0.910atm?
Expert Answer
The gas constant (R) in L atm/mol K is equal to 0.082 L atm/mol K. The mass of 0.250 kg is equivalent to 250 g and 27 0C is equivalent to 300.15 K.
The number of moles of oxygen is calculated as shown in equation (1) where ‘n’ is the number of moles of oxygen gas, 32 g/mol is the molar mass of the O2 gas, ...
