A Goodyear blimp typically contains 5400m^3 of helium (He) at an absolute pressure of 1.1*10^5Pa. The temperature of the helium is 280K. What is the mass (in kg)of the helium in the blimp?

PLEASE GIVE ME SOME IDEAS TO DO IT!!!THANKS A LOT!!!

    I know that I should find an equation, but which one?

  • physics - ,

    P V = n R T

    that gives you the moles of He

    each mole has mass of 4 grams or 4*10^-3 kg
