If 7.68 gram of phosphorous solid is mixed with 1.00 L of Chlorine gas at STP to form P2Cl5 according to the following unbalanced chemical reaction P4 (s) + Cl2 (g) →P2Cl5 (g) The molar mass of P4 is 123.88 g/mol. Predict the molar weight of an unknown gas if 7.24 liters at STP weigh 5.88 grams. The representative particles can be atoms, molecules, or formula units of ionic compounds. If you want to prepare 1.0 litre of 0.5M CaCl2. The molar mass of HCl is 36.46 g/mol. You have the molar mass of CaCl2 = 111.0g/mol. Thus, calculating the molar mass, M of the two gases: But you want to prepare 5.91 litres: Mass required = 5.91*55.5 … Favorite Answer. Answer Save. It's diatomic. 4. Estimate its molar weight. This relationship is frequently used in the laboratory. To determine the molar mass of one chlorine molecule, simply add the molar masses of the two chlorine elements, or multiply the atomic mass by two. B) Which reactant is the limiting reactant? For glucose, C 6 H 12 O 6, the molar mass of each element is: carbon, 12.0107 x 6 = 72.0642 g/mol; hydrogen, 1.007 x 12 = 12.084 g/mol; and oxygen, 15.9994 x 6 = 95.9964 g/mol. If you know the volume of the solution in liters, you can multiply the molarity by the volume in liters to determine the number of moles of solute. 0 0.

Trevor H. Lv 7. 5 years ago.43moles. K-l at P = 1.00 atm. It can be used to convert the mole to mass. 5 years ago. The answers appear after the final question. The density of an unknown gas is 3.62 grams per liter at STP. For this reaction, you need to convert both the given grams of B2H6 and Cl2 to moles to determine which is the limiting reactant. Th Avogadro's number is the number of molecules in one mole of a substance. Once you determine the reactant that will dictate the amount of moles of product being produced, you can then solve for the amount of energy being released. Ask Question + 100. Still have questions? And the most difficult task here is finding out the molar mass of the substance. What Is The … This is because the mass of a substance is dependent on the molecular weight of the substance, which is determined by the number of protons and neutrons in the nucleus of the atom. Balanced equation: 2Na + Cl2 → 2NaCl n = m/M, where: n = mole m = mass M = molar mass Calculate moles Na and Cl2 from given masses and molar masses. Since you have more than enough H2, Cl2 is the limiting reactant. Molar mass of chlorine is 70.9060 g/mol Compound name is chlorine Convert between Cl2 weight and moles
