5) Oxygen gas is collected over water. The total pressure (the O2 pressure + the water vapor pressure) is 765 torr. The temperature of the water is such that the water vapor pressure is 38 torr. What is the partial pressure of the oxygen gas in torr?
A sample of He collected over water at a temperature of 20'C has a pressure of 705 torr. What is the pressure of the dry gas? The vapor pressure of water at 20'C is 17.5 torr
If the volume of wet gas collected over water is 78.0 mL at 20 ∘C and 753 mmHg , what is the volume of dry gas at STP conditions? (The vapor pressure of water at 20 ∘C is 17.5 mmHg.)
Hydrogen produced from a hydrolysis reaction was collected over water. The data is compiled in the table. Total volume of H2(g) collected 96.96 mL Temperature 25.0°C Barometric pressure 742 mmHg Vapor pressure of water at 25.0°C 24.0 mmHg Calculate the moles of hydrogen gas produced by the reaction. moles: mol H2
6. A volume of 310 ml of O2 (g) is collected over water at 20C at a pressure of 738 torr. (a) What is the partial pressure of the O? (b) What would be its volume when dry at STP? (Vapor pressure at 20°C is 17.5 torr) (10) 0 mol N2 exerts a pressure of 800 torr. What is the partial pressure of each gas? (5) 8. A mixture of 2.00 mol H2, 3.00 mol NH3, 64.00 mol Co2, and...
I need help with my homework :) 1. A student reacted 0.0159 g of Al with excess HCI and collected the H2 gas over water against an atmospheric pressure 744 mmHg and a temperature of 22.0°C. Write the net ionic equation for the reaction of Al with HCl. Calculate the volume of the gas. The vapor pressure of water at 22.0°C is 19.8 mmHg. 1. A student reacted 0.0159 g of Al with excess HCI and collected the H2 gas...
A 1,096.9 mL sample of hydrogen gas was collected over water at 25°C and a pressure of 777.6 torr. If the pressure of water vapor is 24.0 torr at 25.0°C, what mass of hydrogen gas (g) was collected?
A sample of hydrogen is collected over water at a temperature of 230C. The pressure inside the tube is determined to be 689 mmHg, and 12.10 mL of gas has been collected. What would the volume of collected hydrogen be at STP? a weird lab decided to use glycerin, a liquid with a density of 1.260 g/mL. If the water level inside the tube was 12.31 cm higher than outside the tube, and the atmospheric pressure measured 728 mmHg, what...
2 Calculate the pressure of the Hydrogen gas collected. Water temperature was 23.0 ° C and the atmospheric pressure was 741.0 mmHg. (Hint the density of Mercury is 13.6 g/mL) H2 gas collected over water 220. mm H20 RT
35 L of a gas were collected over water when the barometer read 547.0 mmHg and the temperature was 40 oC . What volume would the dry gas occupy at standard conditions?
