Answer 1

Volume of 6.5 moles of Helium at STP is 145.6954 L

Step-by-step explanation:

As we know

`pV = nRT`

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 -

`1 * V = 6.5 * 0.08206 * 273.15\\V = 145.6954`Liters

Volume of 6.5 moles of Helium at STP is 145.6954 L
