A large weather balloon filled with helium has a volume of 7.00 x 102 L at STP. Which expression should be used to find the mass
of helium in the balloon?
1 answer:
Answer:
mass of Helium = mole of Helium x Molarmass of Helium
Explanation:
Mole of Helium = volume of Helium/ 22.4dm^3/mol
= 7.00 x 10^2/22.4
= 31.25mol
Mass of Helium = mole of Helium x Molarmass of Helium
= 31.25mol x 4g/mol
= 125g
