6.) A sample of a gas has an
initial volume of 250ml at
1790 mnm H

Expert Solution

Step 1

Calculate the volume of the gas at STP as shown below.

$\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2} V_{2}}{T_{2}} V_{2} = \frac{P_{1}}{P_{2}} \frac{T_{2}}{T_{1}} V_{1}$

The standard temperature and pressure are 273.15 ⁰K and 101.325 kPa.
