# Calculating Average Density of a Bar

## Calculation of Average Density

**Data:**

- Trial 1: Height = 6.50 cm, Diameter = 1.25 cm, Mass = 46.83 g
- Trial 2: Height = 6.45 cm, Diameter = 1.26 cm, Mass = 46.332 g
- Trial 3: Height = 6.44 cm, Diameter = 1.23 cm, Mass = 47.0141 g

To calculate the average density of the bar, we will use the formula:

**Average Density = Mass / Volume**

Let's calculate the average density for each trial:

## Trial 1:

**Mass:**46.83 g

**Volume:**6.50 cm³

Average Density = 46.83 g / 6.50 cm³ = 7.20 g/cm³

## Trial 2:

**Mass:**46.332 g

**Volume:**6.45 cm³

Average Density = 46.332 g / 6.45 cm³ = 7.18 g/cm³

## Trial 3:

**Mass:**47.0141 g

**Volume:**6.44 cm³

Average Density = 47.0141 g / 6.44 cm³ = 7.30 g/cm³
