  5. Physics plzzzzzzzzz help

    so ? A Goodyear blimp typically contains 4770 m3 of helium (He) at an absolute pressure of 1.10 x 105 Pa. The temperature of the helium is 274 K. What is the mass (in kg) of the helium in the blimp? This is just a case of applying the ideal gas law, n = PV/RT. You know the ...
