Question #1a3be

Answer 1

This will be 0.546 mol.

Explanation:

Use the ideal gas law `PV=nRT` and solve for `n`

`n=(PV)/(RT)=((1.00 atm)(12.23L))/((0.0821)(273 K)) = 0.546 "mol"`

Here, I have taken the units of pressure to be atmospheres, as no particular unit was stated, and have chosen the corresponding value of the gas constant R.
