Question

Find the volume of 6.45 moles of gas present at a temperature of 27.0oC and a pressure of 675 torr.

Answer 1

Answer: The volume of the gas is 178.76 L

Step-by-step explanation:

The ideal gas equation is given as:

.......(1)

where

P = pressure of the gas = 675 torr

V = volume of gas = ?

n = number of moles of gas = 6.45 moles

R = Gas constant = 62.36 L.torr/mol.K

T = temperature of the gas =
`27^oC=[27+273]K=300K`

Putting values in equation 1, we get:

`675torr* V=6.45mol* 62.36L.torr/mol.K* 300K\\\\V=(6.45* 62.36* 300)/(675)=178.76 L`

Hence, the volume of the gas is 178.76 L
