Law of conservation of mass: When `4.2 g` of sodioum hydrogen carbone `(NaHCO_(3))` is added to a solution of acertc aacid `(CH_(3) COOH)` weighting `10.0 g` then `2.2 g` of carbon diosxed `(CO_(2))` is released into the atmosphere and the residue ledft weighs `12.0 g`. Show that these observation are in agreement with the law of conservation of mass.
Strategy: Find the sum total of mass of recants before the reaction and sum total of mass of products after the reaction.
