What mass of helium gas is needed to pressurize a 120.0 L tank to 266 atm at 25°C???HELP!?
--------------------------------------…
120 liters/22.4 liters/mole = 5.36 moles at STO.
But we have 226 atm, so that's 226 x 5.36 = 1211.4 moles.
One final correction: 273/(273+25) x 1211.4 = 1109.8 moles, or 4439.2 grams He.
