Question

How do i find the volume of a 0.227 mol sample of CO2 at STP using the ideal gas law?

Answer 1

V= `color(blue)(5.09L)`

Explanation:

STP:
Standard Temperature-273.15 K
Standard Pressure- 1atm=760mmHg=101.3 kPa
And we know that the Gas constant `color(red)(R)` uses 0.0821`(atm*L)/(mol*K)`

The Ideal Gas Law
PV=nRT
Now, we have to find the `color(red)(Volume)` by rearranging the formula to find `color(red)(V)`

`color(red)(V=(nRT)/(P))`

`color(red)(V)=(0.227cancel(mol)*0.0821(cancel(atm)*L)/(cancel(mol)*cancel(K))*273.15cancel(K))/(1cancel(atm))`
`color(red)(V)=?`
