Reacting amount calculations
WebA mole ratio is the ratio between the amounts in moles of any two compounds involved in a balanced chemical reaction. The balance chemical equation provides a comparison of the ratios of the molecules necessary to complete the reaction. We cannot calculate mole ratio for an unbalanced equation.Mole ratios are used as conversion factors between ... WebConvert that number of moles into grams if you are asked for a mass. The calculation looks like this: 1 mol O 2 weighs 2 x 16 = 32 g. 1.60 g is 1.60/32 = 0.0500 mol. The equation …
