Answer:

1.2807 moles

Step-by-step explanation:

From rearranging the equation for the ideal gas equation, you get the equation n=PV/RT, n= moles, P= pressure, V= volume, R= gas constant, T= temperature. Plugging in the numbers and converting kPa to atm and C to K, you get n=1.19418*28/ .0821*318.

Then, you just do the math and get 1.2807 moles.
