A little homework Help…?

11. Karen measures the volume of a gas at 200 K and 100 kPa. To correct her measurement to standard temperature and pressure (STP), what must she do?

Answer 1

This is chemistry, not math.

make a volume correction based on a higher temperature of 273 K
1.51 L
2.0 L
The gas generated by two antacid tablets has a smaller volume.
?
?
?
406 kPa
It reduces to one-half the original volume.
?

Answer 2

11. make a volume correction based on a higher temperature of 273 K (technically, 273.15 K).

12. 1.51L

13. 2.0L

14. The gas generated by two antacid tablets has a smaller volume.

15. 901K

16. V1/T1 = V2/T2

17. The student did not work with absolute temperatures, and the answer should be 85 kPa.

18. 406 kPa

19. It reduces to one-half the original volume.

20. Boyle’s Law
