So2 molar mass how to#

The molar mass of Cl 2 (which we get from the atomic mass of Cl from the periodic table) is 70.90 g/mol.

So2 molar mass how to#

We know how to do this by simply using the molar mass of Cl 2 as a conversion factor. So to use the balanced chemical equation to relate an amount of Cl 2 to an amount of AlCl 3, we need to convert the given amount of Cl 2 into moles.

How can we determine how many moles of AlCl 3 we will get when the reaction is complete? First and foremost, chemical equations are not balanced in terms of grams they are balanced in terms of moles. We can add that conversion factor as another step in a calculation to make a mole-mass calculation, where we start with a given number of moles of a substance and calculate the mass of another substance involved in the chemical equation, or vice versa.įor example, suppose we have the balanced chemical equation: Recall that the molar mass can be determined from a chemical formula and used as a conversion factor. Mole-mole calculations are not the only type of calculations that can be performed using balanced chemical equations. From a given mass of a substance, calculate the mass of another substance involved using the balanced chemical equation.From a given mass of a substance, calculate the moles of another substance involved using the balanced chemical equation.From a given number of moles of a substance, calculate the mass of another substance involved using the balanced chemical equation.
