Chemistry worksheet featuring stoichiometry problems on balancing equations and calculating moles and masses.

A worksheet titled "Mass/Mole and Mass Problems" with three chemistry problems involving stoichiometry, including balancing equations and calculating moles and grams of reactants and products. The first problem shows a balanced equation for the formation of ammonia from nitrogen and hydrogen, with a calculation for moles of ammonia produced from 6.0 moles of nitrogen. The second problem involves balancing the reaction between aluminum and zinc chloride, followed by a calculation for moles of zinc chloride reacting with 45.0 grams of aluminum. The third problem asks for the grams of iodine form
