Answer 1

Answer:

1.7 g/mL

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume}$

From the question

volume = final volume of water - initial volume of water

volume = 16.3 - 15 = 1.3 mL

We have

$density = \frac{2.21}{1.3} = 1.7$

We have the final answer as

1.7 g/mL
