Question

the vinegar was used to remove the shell form the raw egg. what other effect(s) did the vinegar have on the egg? a the vinegar solution was hypotonic, causing the egg to gain mass. b the vinegar solution was hypotonic, causing the egg to lose mass. c the vinegar solution was hypertonic, causing the egg to gain mass. d the vinegar solution was isotonic to the egg so the mass remained constant.

Explanation:

In a hypotonic solution, water moves into the cell (or in this case the egg) due to osmosis. Vinegar is hypotonic to the egg's interior, so water enters the egg causing it to gain mass.

Answer:

A. The vinegar solution was hypotonic, causing the egg to gain mass.
