Question

At s.t.p a certain mass of gas occupies a volume of 690cm^3. Find it's volume at a temperature of 54°C and pressure of 750mmHg

Answer 1

750mmHg=1atm=1bar - standart pressure.

273,15 K=0 C° standart temperature

Gas's laws T/V=const (if P=const)

273,15/690=327,15/V_find

V_find=826,4 cm3 volume
