Answer:
<h2>Density = 2.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of rock = 12.947 g
Volume of rock = final volume of water - initial volume of water
Volume = 46.2 mL - 41.3 mL = 4.9 mL
Substitute the values into the the above formula and solve for the density
That's
We have the final answer as
<h3>Density = 2.64 g/mL</h3>
