The pressure of a container of fluorine gas with a volume of 1.5L is 678mmHg at 55.0*C.

a. If the volume of the fluorine gas increases to 5.0L, what would be the pressure of the gas in atm? The amount and tempature of gas are consistant.

b.How many grams of fluorine gas are in the container?

  • Chemistry -

    a. P1V1 = P2V2. Solve for P2 and convert to atm. atm = mmHg/760
    b. Use PV = nRT and solve for n = number of moles of fluorine. Then n = grams/molar mass. Solve for grams.
