WebA compound is found to be 30.45% N and 69.55 % O by mass. If 1.63 g of this compound occupy 389. mL at 0.00°C and 775 mm Hg, what is the molecular formula of the compound? N2O4. What is the mole fraction of CO in a container with a H2 mole fraction of 0.22 and an O2 mole fraction. WebJun 5, 2016 · We are given volume and the proportionality constant, R, is equal to 0.0821 L atm/ mol K. Now all we have to do is rearrange the equation and solve for n like so: n = PV/RT. n = (1 atm) (5 L) / (0.0821 L atm/ mol K) (273K) Which gives you 0.223 moles of hydrogen gas. I hope this makes sense, and here is a link for additional help!
