<h3>The answer is 4.15 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of object = 8.3 g
volume = final volume of water - initial volume of water
volume = 8 - 6 = 2 mL
So we have

We have the final answer as
<h3>4.15 g/mL</h3>
Hope this helps you
Answer:
Explanation:
In weight/volume (w/v) terms,
1 ppm = 1g m-3 = 1 mg L-1 = 1 μg mL-1
200 mL = 0.2 L
15 / 0.2 mg L-1 =75 ppm
