Mr. Holmes is busy making a paper mache volcano that he is sure is going to win the national science fair contest. He only has room in the volcano's vent to put 100g of baking soda and 100ml of vinegar.

Mr. Holmes has 4 different concentrations of vinegar in his lab. The active ingredient in vinegar is acetic acid C2H4O2. Which concentration would give the most intense eruption in the volcano?

Bottle 1 shows that it has 44g of acetic acid in the 1L bottle.

Bottle 2 shows the vinegar has a molarity of 2M acetic acid

Bottle 3 shows it is 4% acetic acid by mass.

Bottle 4 when measured shows a pH of 7.

Bronson Glenn · Answer 1

Bottle 2 shows the vinegar has a molarity of 2M acetic acid

Explanation:

2M of acetic acid has higher concentration of acetic acid as compared to other vinegar. In 2M of acetic acid is equals to 120 gram of acetic acid in 500 ml of water which is quiet higher than other concentration of acetic acid in vinegar which is 4%. So Mr. Holmes has to use 2M of acetic acid which will produced high intense eruption in the volcano and win the national science fair contest.
