In the first cell, 42.51 mL of hydrogen gas were formed at the cathode.The temperature was 21.5C and the vapor pressure of water at this temperature is 19.240 torr. The Barometric pressure was 758.8 mm Hg and the height of water in the buret above the level of water in the beaker was 8.2 cm. Calculate: a. Partial Pressure of Hydrogen (H2) in buret (PH2 = Barometric – VP – Pheight) (The pressure due to the height of water still...
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...
