The balanced equation below represents the reaction between magnesium metal and hydrochloric acid to produce aqueous magnesium chloride and hydrogen gas.
Mg (s) + 2HCl (aq) = = > MgCl2 (aq) + H2 (g)
A piece of Mg (s) has a volume of 0.0640 cubic centimeters. This piece of Mg (s) reacts completely with HCl (aq) to produce H2 (g). The H2 (g) produced has a volume of 112 milliliters and a pressure of 1.00 atmosphere at 298 K.
65 The volume of the piece of Mg (s) is expressed to what number of significant figures?
