Calculate the number of moles of gas contained in a 10.0L tank at 22 degree C and 105 atm (R = 0.08206 L atm / Kmol) 1.71 times 10-3 mol 0.0231 mol 1.03 mol 43.4 mol 582 mol Calculate the grams of SO2 gas present at STP in a 5.9 L container. 0.24 g 0.26 g 15 g 17 g 67 g A mixture of three gases has a total pressure of 1,380 mmHg at 298 K. The mixture is analyzed and is found to contain 1.27 mol CO 2, 3.04 mol CO4 and 1.50 mol AR. What is the partial pressure of Ar? 0.258 atm 301 mmHg 356 mmHg 5.345 mmHg 8.020 mmHg Which one of the following sets of quantum numbers is not possible? The orbital diagram for a ground-state nitrogen atom is Which element has the following ground state electron configuration?

Explanation / Answer

15)PV=nRt

or 105*10=n*(1/12)*(273+22)

or n=43.4

so the correct option is D

16)mass=64*(5.9/22.4)

=17 grams

so the correct option is D

17)P=(1.5)/(1.5+3.04+1.27)*1380

=356 mm Hg

so the correct option is C

18)the correct nswer is B

since m can rage only betweel +l to -l .

19)the correct answer is A

20)the answer is W
