Question

Carbon dioxide gas is collected at 27.0 oC in an evacuated flask with a measured volume of 30.0L. When all the gas has been collected, the pressure in the flask is measured to be 0.480atm. Calculate the mass and number of moles of carbon dioxide gas that were collected.

Answer 1

`M_(CO_2)= 25.7g`

Step-by-step explanation:

From the question we are told that:

Temperature
`T=27.0`

Volume
`V=30L`

Pressure
`P=0.480atm`

Generally the equation for Ideal gas is mathematically given by

PV=nRT

Therefore

`n=(0.480 x 30)/(0.08205 x 300)`

`n=0.59moles`

Generally Mass of CO2 is given as

`M_(CO_2)= 0.59 * 44 g/mol`

`M_(CO_2)= 25.7g`
