Answer:
0.51643192
Step-by-step explanation:
If the formula for density is d = m/v, then the formula now will be v = m/d.
Then, if you impute the numbers into the letters, that should come to v = 2.2/4.26.
That equals 0.51643192. Reduce it to however many places you need to, and that will be your answer. Make sure to place g/mL after your answer, too.
