We set up the problem to solve for mol product; the general equation is: Web( 3 votes) Richard 2 years ago Yes you are correct, Sal should not have rounded prematurely like that for the moles of glucose and should have rounded only at his final answer. So doing the same calculations Sal did, but only rounding until the very end should result in 26.6g. WebSolution. Referring to the balanced chemical equation, the stoichiometric factor relating the two substances of interest is 3 mol I 2 2 mol Al. The molar amount of iodine is derived by multiplying the provided molar amount of aluminum by this factor: mol I 2 = 0.429 mol Al × 3 mol I 2 2 mol Al = 0.644 mol I 2. port mor islay
