Q Question 1 A pressure of 0.500 atm is the same as a pressure of of mm Hg Question 2 A fixed amount of gas at 25.0 °C occupies a volume of 10.0 L when the pressure is 751 torr. Use Boyle's law to calculate the pressure (torr) when the volume is reduced to 7.25 L at a constant temperature of 25.0 °C. Question 3 A balloon originally had a volume of 4.39 L at 44 °C and a pressure of 729 torr. The balloon must be cooled to °C to reduce its volume to 3.99 L (at constant pressure). Question 4 A 0.325 L flask filled with gas at 0.851 atm and 19 °C contains mol of gas. Question 5 How many moles of gas are there in a 36.3 L container at 25.2 °C and 570.3 mm Hg? Question 6 The density of nitric oxide (NO) gas at 0.970 atm and 34.9 °C is g/L.
