Question

You add 9.0g of iron to 23.50 mL of water and observe that the volume of iron and water together is 24.64 mL Calculate the density of rain

Answer 1

To calculate the density of the iron added to water, we can use the formula density = mass/volume. The mass of the iron is 9.0g and the volume of the iron is 1.14 mL. Therefore, the density of the iron is 7.89 g/mL.

Step-by-step explanation:

To calculate the density of a substance, you need to know its mass and volume. In this case, the mass of iron added is 9.0g and the volume of water is 23.50 mL. After adding the iron, the volume of the mixture is 24.64 mL.

First, we need to determine the volume of the iron. Since the volume of the iron and water together is 24.64 mL, and the volume of water is 23.50 mL, the volume of the iron is 24.64 mL - 23.50 mL = 1.14 mL.

Next, we can calculate the density using the formula: density = mass/volume. The mass of the iron is 9.0g and the volume is 1.14 mL. Plugging the values into the formula, we get density = 9.0g/1.14 mL = 7.89 g/mL.
