Calculator gives the density at 125 °F and 14.5 psia: 0.00465 [lb m /ft 3] GAS SAMPLE DATA Volume of sample 90.0 mL Temperature 25 C Atmospheric Pressure 745 mm Hg Equilibrium Vapor Pressure of H 2 O (25 C) 23.8 mm Hg (a) Calculate the number of moles of hydrogen gas collected. (b) Calculate the number of molecules of water vapor in the sample of gas.

A 44.7 mL sample of oxygen is To what temperature does 736 mL of hydrogen originally at 15.0°C A rigid canister holds 50.0 L of helium gas at 32.0°C
A sample of 40.0 mL of hydrogen is collected by water displacement at a temperature of 20 degrees Celcius. The barometer reads 751 torr. What is the volume of the hydrogen at STP (standard temperature and pressure)? Chemistry.

However, the volume does not have the proper units since it is given in terms of milliliters instead of liters. We can convert 500 mL into liters by using the conversion factor 1000mL = 1L. When 500 mL is divided by 1000 mL/L, we obtain a volume of 0.50 L. Now Determine the volume of hydrogen gas needed to make 8 L of water vapor. Calculate the volume of chlorine gas at STP that is required to completely react with 3.50 g of silver, using the following equation: 2Ag (s) + Cl2 (g) → 2AgCl (s).
