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.

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. 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.
