How many tums tablets each 500mg CaCO3 will it take to neutralize quart of Vinegar 0.83 moler (CH3COOH)

Answer 1

assuming a quart is one liter, so you have .83 moles of acid in the vinegar.
CaCO3 + 2CH3COOH>>CO2 + H2O + C4H6O4Ca Calcium Acetate
so it takes one mole of calcium carbonate to neutralize 2 moles of acid.
You have .83 moles acid, so you need 0.415 moles, or .415*100 grams of tablets.
How many tablets? n*0.500 grams=41.5 or n= .... you do it.
