A100 ml graduated cylinder with an inside diameter of 3.2 cm contains 34.0 g of gasoline and 34.0 g of water. what is the combined height of the two liquid layers

The volume of cylinder is 100 mL, inner diameter is 3.2 cm thus, radius will be:

Volume of layer formed=...... (1)

Volume of layer is also equal to sum of volume of gasoline and water.

Density of gasoline is and mass is 34 g thus, volume of gasoline will be:

Now, density of water is and mass is 34 g thus, volume of water will be:

Adding both the volumes, volume of layer will be:

Putting the values in equation (1) to solve for height of the layer,

Thus, height of layer is 10.25 cm
