Question

A certain mass of oxygen has a volume of 5m^3 at 27°C.If the pressures remain constant,What will be its volume at 77°C?

I need the full answer with working ​

Answer 1

Answer:

With a pressure, for instance, of 4 atmospheres, and a volume of 5 liters yields 4 x 5 = 20. Divide the result by the number of moles of gas. If, for instance, the gas contains 2 moles of molecules: 20 / 2 = 10. Divide the result by the gas constant, which is 0.08206 L atm/mol K: 10 / 0.08206 = 121.86.
