Balance the chemical equation. List out the known variables in the problem. These include the given mass of the reactants. Find the molar mass of the reactants from the periodic table. Use stoichiometry to convert the mass of the reactants to the mass of the products. Check: the mass ...
If the given chemical compound is complex (say Ax(ByCz)n) and we need to compute its molar mass M, then we'll use the table of molar masses and simplify the required value using the following formula. Afterward, multiply the obtained value by the number of moles to determine the numbe...
A compound of C, H, N, O Determine the empirical formula from the percent composition by mass: 19.8% C, 2.50% H, 11.6% N What is its molecular formula given that its molar mass is about 120g? Calculate the percent by mass of the element lis...
There are other easy ways to express the concentration of a chemical solution. Parts per million and parts per billion are used primarily for extremely dilute solutions. g/L= grams per liter = mass of solute / volume of solution F= formality = formula weight units per liter of solution ...
