|

Volume of 6.5 moles of Helium at STP is 145.6954 L

Explanation:

As we know

At STP, temperature is  273.15 K  and pressure is  1 atm

n is the number of moles which is equal to 6.5

R is the gas constant = 0.08206 L atm/K mol

Substituting the given values in above equation, we get -

Liters

Volume of 6.5 moles of Helium at STP is 145.6954 L
