convert the given concentrations into molarity. here the amount of pcl 5 before the reaction is 6 moles and the volume of the reaction vessel is 1 l. therefore, the concentration of pcl 5 is 6/1 moles/litre = 6 m. step 3 : make a note of the initial concentration and the change ...
they give you the molecular weights of each component, and you can find the molecular weight of the mixture by just adding the molecular weights. since the masses are in grams, and moelcular weight is in g/mol, if you divide the mass by molecular weight you get just mo...

% Concentration Definition: The percent of the solution that is solute. Units: Mass in grams (g); Volume in millilitres (mL). Analogy: Your grade on a test is the percent of the test that you got correct. There are 100 questions on the test = The solution is 100g Your got 45 corr...
