Web8 nov. 2024 · First, determine how many moles are present in 3 grams of KCl. Start by looking up the number of grams per mole of potassium and chlorine on a periodic table. Then add them together to get the grams per mole for KCl. K = 39.1 g/mol; Cl = 35.5 g/mol; KCl = 39.1 + 35.5 = 74.6 g/mol; For 3 grams of KCl, the number of moles is: Web4.5M = x mol / .325g. x = 1.4625 mol x (32g / 1 mol CH3OH) = 47 g.
