Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of 3.16 cm contains 34.6 g of heptane and 34.0 g of water. What is the combined height of the two liquid layers in the cylinder? The volume of a cylinder is π r2h, where r is the radius and h is the height.

Explanation:

Hello,

In this case, considering the density and mass of both water and heptane we first compute the volume of each one:

Now, the total volume is:

Which is equal to:

Then, by knowing that the volume of a cylinder is πr²h or π(D/2)²h, we solve for the height as follows:
