when 8.4 g of NaHCO_(3) is added to a:solution of CH_(3)COOH Weighing 20g. it is observed that 4.4 g of CO_(2) is released into atmosphere and a residue is left behind. Calculate the mass of residue by applying law of conservation of mass.

When 4.2 g NaHCO_(3) is added to a solution of CH_(3)COOH (acetic acid) weighing 10 g , it is observed that 2.2 g of CO_(2) is released to the atmosphere. The residue is found to weigh 12.0 g . Show that these observations are in agreement with the law of conservation of mass.

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.
