1 | 2 |'. 3 .| 4 5 I| 6 1. A chemist collects 372 cm³ of gas over water at 90°C and 111.0 kPa. What volume would the dry gas occupy at 2°C and 98.0 kPa? Determine how many dm of CO, at STP can be produced from 15.7 grams of Fe,O, according 3 CO (g) 2. to the following reaction: Fe,O, (cr) 2 Fe (cr) 3 CO, (g) + 3. A 757 mL sample of a gas is collected over water at 21.0°C and 87.3 kPa. What volume will the dry gas occupy at STP? 4. A 43.3 cm3 sample of a gas is collected over water at 70.0°C and 121 kPa. What volume will the dry gas occupy at 25°C and standard pressure? 5. From your textbook - page 421 #67 6. From your textbook - page 421 #68 7. From your textbook - page 421 #72 8. From your textbook - page 421 #74 COMBINED GAS LAW - here are some questions that describe a sample of a gas that undergoes a change. In this case, the sample will experience a change in pressure and temperature. Combined Gas Law combines both Boyle's and Charles' Law. (P,V,)/T, = (P2V)/T, Use the above equation to solve the following problems: 9. A 51.7 cm sample of a gas at 27°C and 90.9 kPa would occupy what volume at STP? 10. A volume of neon gas measured at -12°C and 78.6 kPa is to be corrected to correspond to the volume the gas would occupy at 35°C and 107 kPa.
