Question

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

Answer 1

Answer:

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

Explanation:

Given:

Temperature = 27°C

To make it into kelvin   = 27+273

 = 300K

Pressure  =740mm Hg

to make it in atm.  = $\frac{740}{760}$

= 0.973atm

n   = 2.3 moles

Volume of gas =?

 As we know according to the formula

 PV   = nRT

$V= \frac{nRT}{P}$

On substituting the values

 = $\frac{2.3\times0.0827\times300}{0.973}$

= 58.22 L

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