Complete Question
In experiment 1, how many moles of benzoic acid are present? How many moles of sodium bicarbonate are contained in 1 ml of 10% aqueous solution? (A 10% solution has 1 gram of solute in 9 mL of solvent.) Is the amount of sodium bicarbonate sufficient to react with benzoic acid. The amount of Benzoic Acid in ex. 1 is 0.060 grams
Answer:
No of moles of benzoic acid present
Number of moles of sodium bicarbonate present
Yes the is sufficient sodium bicarbonate to react with Benzoic acid
Explanation:
From the question we are told that
The mass of Benzoic acid is
The number of moles of Benzoic acid is
where is the molar mass of Benzoic acid which is a constant with values
So
the density of the solution of sodium bicarbonate is
The mass of sodium bicarbonate is
The molar mass of sodium bicarbonate is a constant with value
The number of moles of sodium bicarbonate is
So the number of moles of Benzoic acid and sodium bicarbonate that react are approximately in a 1:1 ratio so we can conclude that there is sufficient sodium bicarbonate to react Benzoic acid
