Question

A gas occupies a volume of 410 mL at 27°C and 740 mm Hg pressure. Calculate the volume the gas

would occupy at 250.°C and 680 mm Hg pressure.

Answer 1

The volume of gas is 58.22 L which will occupy at 250.°C and 680 mm Hg pressure.

Step-by-step explanation:

Given:

Temperature = 27°C

To make it into kelvin = 27+273

= 300K

Pressure =740mm Hg

to make it in atm. =
`(740)/(760)`

= 0.973atm

n = 2.3 moles

Volume of gas =?

As we know according to the formula

PV = nRT

`V= (nRT)/(P)`

On substituting the values

=
`(2.3*0.0827*300)/(0.973)`

= 58.22 L

Therefore, 58.22L volume of gas will occupy at 250.°C and 680 mm Hg pressure.
