... In Section 10.2, it was shown that 46.0 g of sodium were needed to exactly react with 71.0 g of chlorine gas. Supposing, instead, only 10.0 g of sodium were available, what mass of chlorine would be necessary to use up the 10.0 g of sodium? This is where the application of mole calculations becomes ...

... The Law of Conservation of Mass was officially established in the year 1789 by the French Chemist, Antoine Lavoisier. The Law of Conservation of Mass states that mass is neither lost nor gained in chemical reactions, it states that it simply changes form. For that reason, if you had a certain number ...
