Step-by-step explanation

The teacher wants 100 extra barium bromide so they will have ...

500-100 = 400

Let's how many groups of 4 they have

32/4 = 8

Let's distribute the barium bromide equally.

400/8 = 50

Since it takes 52 barium bromide to saturate 50 mL of water, they will not have enough.
