What is the number of moles in 500 L of He gas at STP? a) 0.05 mol b) 0.2 mol c) 22 mol d) 90 mol How many moles of N2 do you need to make 1.76 moles of NH3? How many grams are in 0.00703 moles of H2O? How many grams ...
2 H2 (g) + O2 (g) \to 2 H2O (l) a. If 3.5 moles of oxygen gas react with hydrogen, how many moles of water vapor will form? b. If 54.3 grams of water vapor form, how many moles of hydrogen gas are needed? c. How many gr...
= 2 mol = 1 mol = 2 molThis ratio is the ratio of stoichiometric numbers in the equation. So the equation is: 2H2 + O2 -->2H2O We can still deduce the stoichiometry of this reaction even if we do not know the mass of oxygen that reacted. The ratio of hydrogen to ...
The total mass of a single hydrogen diatomic molecule (H2) is 2. 016 AMU. A mol of hydrogen gas has a mass of 2.016 grams. In that 2.016 gram mass is Avogadro’s number of H2 molecules because that is the way hydrogen comes. A mol of water is 18.016 grams because each water ...

Answer to: A 10.00 L vessel containing CO_2 has an internal pressure of 20.0 atm at 273 K. Calculate the number of moles of gas using the virial...
Finding Number of Moles with Ideal Gas Equation I want to find the number of moles and I have the ideal gas equation as : n = PV/RT However I think I'm using the wrong units to find it, I want the answers in moles. n = (1 Pa * 1 m^3) /(8.314 JK^-1 mol^-1 * 1K) ...
Specfically a mole is 6.02 x 1023 atoms or molecules of an element or compound, respectively. This value is known as Avogadro's number. Answer and Explanation: There are 4.2 moles of chlorine in this sample. 4.2molCl×1molCl1molHCl=4.2molCl Since there is......
