Aluminum metal reacts with hydrochloric acid to form hydrogen gas and an aluminum chloride solution in this investigation, you will predict the mass of hydrogen gas produced by a given amount of reactants, then measure the amount, and compare them. Cp chemistry theodore roosevelt high school lab #2-5 stoichiometry lab introduction in chemical reactions, the actual masses of substances used are proportional to their molar masses therefore, it’s possible to predict the number of grams of a given product that will be formed in a reaction if you know the mass of any one of the reactants. Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry it is a super technical-sounding word that simply means using ratios from the balanced equation in this article, we will discuss how to use mole ratios to calculate the amount of reactants needed for a reaction balanced reactions and.

Stoichiometry – limiting reagent laboratory name_____ section_____ 2 moles) the theoretical yield (in grams) is obtained by multiplying the theoretical yield in moles by.
Stoichiometry lab report aim: to determine what solid product is produced in the decomposition of nahco3, based on the pre-calculated mass of the solid products versus the mass found in the experiment.
There is a traditional stoichiometry lab i have done before it involves adding dilute hydrochloric acid to sodium bicarbonate, boiling off the fluid and then getting the mass of the sodium chloride students then can solve the percent yield for the sodium chloride based on the amount of sodium bicarbonate they use. Could you please help me with the following questions i really only need help with the first one, but if you could help with the others, that would just be great :) thanks 1) if we mix 25 grams of sodium bromide with a large amount of potassium chloride, what will our theoretical yield of sodium chloride be 2) if our actual yield. Stoichiometry lab essay stoichiometry lab by: james stewart purpose: to calculate mole ratios introduction: there are two types of chemical analysis qualitative analysis which is the identification of a substance present in a material, and qualitative analysis which measures the amount of the substance.
