1.) In this experiment, if the carboxylic acid is benzoic acid, how many moles of benzoic acid are present (assume an equal portion of each component)? How many moles of sodium bicarbonate are contained in 1 mL of a saturated aqueous sodium bicarbonate. Is the amount of sodium bicarbonate sufficient to react with all of the benzoic acid?
molar mass of Benzoic acid =122 gm, moles of benzoic acid in 0.1385 gm= mass/molar mass= 0.1385/122= 0.001135
Homework Answers
1 mole of sodium bicarbonate reacts with 1 mol of benzoic acid.
Solubility of NaHCO3 = 69 g / Liter = 0.069 g / ml
Moles of NaHCO3 = mass / molar mass = 0.069 / 84 = 8.21 * 10-4 mol
This si not enough to react with all of the benzoic acid

In a bath bomb experiment, 50 ml of sodium bicarbonate is used along with 25 ml of citric acid and 15ml of cooking oil. When the bath bomb is formed and set to dry, it will be dropped in water to observe the reaction. My question is how can I convert 50 ml of sodium bicarbonate and 25 ml of citric acid into grams to get the moles. And is the correct molar ratio 3:1 or is it 2:1, because...
