Answer:

The amount of water must be added to this task = 60 $cm^{3}$

Step-by-step explanation:

Let amount of water added = x $cm^{3}$

Then from the given conditions

A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So

90 (0.05) = 0.03 ( 90 + x )

4.5 = 2.7 + 0.03 x

0.03 x = 1.8

x = 60 $cm^{3}$

Therefore the amount of water must be added to this task = 60 $cm^{3}$
