WebWell, each hydrogen atom is 1.008 grams per mole, but each molecule of hydrogen has two hydrogens in it, so it's gonna be two times six, so 2.016. 2.016 grams per mole or one mole for every 2.016 grams. And so this is going to be approximately equal to, get the calculator out again, 65 divided by 2.016 is equal is to that. WebSolution. Compute the provided molar amounts of reactants, and then compare these amounts to the balanced equation to identify the limiting reactant. m o l S i = 2.00 g S i × 1 m o l S i 28.09 g S i = 0.0712 m o l S i. …
