Solved The chemical formula for sodium bromide is NaBr
WebFirst, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 … WebThe chemical formula for sodium bromide is NaBr. A chemist determined by measurements that 0.090 moles of sodium bromide participate in a chemical reaction. Calculate the mass of sodium bromide that participates. Be sure your answer has the correct number of significant digits. 18.6 g NaBr 4.65 g NaBr None of the options are correct 9.3 g NaBr ... darth cronus
Sodium Bromide - Structure, Properties and Uses of …
WebJan 3, 2024 · As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass. WebThe molar mass of a compound tells you the mass of 1 mole of that substance. In other words, it tells you the number of grams per mole of a compound. The units for molar mass are, therefore, grams/mole. To find the molar mass of a compound: 1. Use the chemical formula to determine the number of each type of atom present in the compound. 2. WebEnter a chemical formula to calculate its molar mass and elemental composition: Molar mass of Br2 is 159.8080 g/mol Compound name is bromine. Convert between Br2 weight and moles. Compound Moles ... Na + Br 2 = NaBr: synthesis: Al + Br 2 = AlBr 3: synthesis: H 2 + Br 2 = HBr: synthesis: Formula in Hill system is Br2: bissell shampoo for pets
