1. Which solutions were hypotonic?

.2M, .3M, .4M *They all had a positive

average change in mass, which means the cells got larger.

2. Which solutions were hypertonic? .5M, .6M, .7M *They all had a negative average

change in mass, which means the cells got smaller.

3. If Bill & Ted created a isotonic solution, the concentration should be .45M.

**it should produce a neutral number.
