For example, (NH 4) 2 S has a molecular weight of (2 x 14.01) + (8 x 1.01) + (1 x 32.07) = 68.17 g/mol.Solution: Using the generic expression to convert g to atoms: Number of Atoms = (Given Mass/Molar Mass) * Avogadro’s Number. Number of Atoms = (78/40.078) * 6.02 * 10^ {23} Number of Atoms = 1.9462 * 6.02 * 10^ {23} Number of Atoms = 1.171 * 10^ {+24} For further verification, you can let this grams to atoms calculator do that for you in seconds.Stoichiometry Problems. The solutions are from a sampling of problems from our Interactive Stoichiometry Problem Set. Problem #1 - Converting Moles to Moles. Problem #4 - Converting Liters to Moles. Problem #8 - Converting Grams to Moles. Problem #10 - Converting Liters to Moles. Problem #11 - Converting Liters to Liters.How many grams of N 2 are required to react completely with 9.47 grams of H 2? N2(g)+ 3 H 2(g) → 2 NH 3(g) Stoichiometry Chapter 4 Given: 9.47g H 2 Find: g N 2 Conversion factors: molar mass , molar ratio g N 2 = 9.47 g H 2 x 1 mol H 2 x 1 mol N 2 x 28.01g N 2 2.016 g H 2 3 mol H 2 1 molN2 = 43.9 g N 2 Stoichiometry CH 4 + 2 O 2 → CO 2 + 2 H 2OShare a link to this widget: More. Embed this widget »How many liters of hydrogen, H2, are needed to react with 10 liters of nitrogen gas in the reaction forming ammonia? $$\ce{3 H2(g) + N2(g) -> 2 NH3(g)}$$ My try:: Because we have 10 L of nitrogen gas, we have 10/22.4 moles = 0.446 moles of nitrogen gas, and thus need 0.446 * 3 = 1.338 moles of hydrogen gas.To convert from moles of A to mass of B in a stoichiometry problem, the following steps are followed: Study with Quizlet and memorize flashcards containing terms like Mass A ---> Moles A----> Moles B---> Mass B, 1.75 mol, 4.49 moles and more.Standard temperature and pressure (STP) means a temperature of 273.15 K (0 °C or 32 °F) and a pressure of 1 atm (101.35 kPa). In practice, this corresponds to the freezing point of pure water at atmospheric pressure at sea level. At STP, one mole of gas occupies exactly 22.4 liters of volume (molar volume).3) If asked to find grams, use MM as your conversion factor to get to grams of the unknown -If asked to find volume, use molar volume to get to liters of the unknown Example: How many liters of oxygen gas are needed to react with 0.234 grams of SO 2 gas at STP? 2 SO 2 (g) + O 2 (g) 3 (g) Answer: 0.234 g SO 2 (1 mol SO2 64.07 g SO2) (1 mol O2Lesson 2: Stoichiometry. Stoichiometry. Worked example: Calculating amounts of reactants and products. Worked example: Relating reaction stoichiometry and the ideal gas law. Converting moles and mass. Ideal stoichiometry.
