magnesium hydroxide Mg(OH)2 is an antacid that is used to relieve indigestion, sour stomach and hurtburn. it can be prepared by reacting magnesium chloride, MgCL2 and sodium hydroxide, NaOH with the by-product of sodium chlrodie, Nacl. in an experiment, a student allowed 15.1g of MgCL2 to react with 9.35 g NaOH. Calculate the mass in grams of Mg(OH)2 that could be obtained at the end of the experiment.

Acompound is found to contain 6.1% hydrogen and 93.9% oxygen. find it’s empirical formula.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
