pressure H2 = 750 - 17.5 = 732.5 torr => 732.5 / 760= 0.964 atm. p1V1 / T1 = p2V2 / T2 ( combined gas law) at STp : p = 1 atm and T = 273 K. 0.964 x 0.032 L / 293 K = 1 atm x V2 / 273 K. V2 = 0.0287 L => 28.7 mL. 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. A 32.0 mL sample of hydrogen is collected over water at 20.0 degrees celcius and 750.0 torr.

(b) Calculate the number of molecules of water vapor in the sample of gas. 2015-11-04 · "2.63 g" One way to approach this problem is to determine the percent composition of hydrogen in water. You know that one water molecule contains one oxygen atom two hydrogen atoms This means that every mole of water molecules will contain 2 moles of hydrogen and 1 mole of oxygen atoms. To find the percent composition of hydrogen in water, use the molar mass of water and that of hydrogen (2 xx A sample of 0.100 mol magnesium metal and an excess of aqueous hydrochloric acid are combined and react to completion.
