9. In a laboratory experiment, 259 mL of gas was collected over water at 24 °C and 751 torr Calulat the volume that the dry gas would occupy at STP. (The vapor pressure of water at 24 °C is 22.4 torr.) A sample of neon effuses from a container in 76 seconds. The same amount of an unknown noble gas requires 155 seconds. Identify the gas. 10. 82 ri si

50 L of a gas were collected over water when the barometer read 550.0 mmHg and the temperature was 22°C. What volume would the dry gas occupy at standard conditions?
A volume of 30.0 mL of nitrogen gas was collected over water at 24.0°C and 0.98 atm. The vapor pressure of water at this temperature is 0.03 atm. a. What is the partial pressure of the nitrogen gas sample, (use Dalton's law)? b. What would the new volume of this gas be at STP. (Use the combined gas law)?
