6. What volume will 9.38g of the mineral quartz (silicon dioxide SiO2)
Tcecarenko [31]

Answer:

The answer is

<h2>3.54 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question

mass = 9.38 g

density = 2.65 g/cm³

The volume of the quartz is

volume =  \frac{9.38}{2.65}  \\  = 3.539622641...

We have the final answer as

<h3>3.54 mL</h3>

Hope this helps you
