Question

2) Consider a sample of gas that occupies 23.1 L at 1.13 atm. What volume will the same sample occupy if the pressure is increased to 3.05 atm while the temperature is held constant?

3) A fixed sample of gas occupies 25.9 mL at 211.3 K. What volume will the gas occupy at 336.6 K?

4) A fixed sample of gas exerts a pressure of 580 Torr at 284 K. What will the pressure be (in atm) if the temperature is reduced to 176 K (assuming the volume is held constant)?

5)A fixed sample of gas occupies 21.7 L at 55.9 oC and 0.622 atm. If the gas expands to 42.8 L and the temperature drops to 28 oC, what will the new pressure be?

6) How many moles of gas are contained in a sample of gas that occupies 16.1 L at 1.15 atm and 257.7 K?

7) H2S (g) can be generated by the following reaction: 2 HCl(aq) + FeS(s) → FeCl2(aq) + H2S(g) What volume (at STP) of H2S gas can be generated from 20.9 mL of 0.403 M HCl and an excess of FeS?
