Question

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!!!

Answer 1

I would find an equation to fit this question.

Answer 2

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

Answer 3

P V = n R T

that gives you the moles of He

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