Calculate the mass in grams of 2.74L of CO gas at 33 degrees celcius and 126.0 kPa

Question

I got 3.75 grams
Is this right please
Thanks

Answer 1

My answer is 3.799 g which would round to 3.80. The difference COULD be the conversion from kPa to atm. I used 101.325 and I used 28 for the molar mass CO.

Answer 2

I believe that you are right due to the conversion difference and the fact that none of the other answer are even remotly close !!!
Thanks DR BOB
