# The Density of a Sample of Pewter Alloy

## What is the density of a sample of the alloy pewter, (a mixture of tin and copper or lead) if a 7.11 cm^3 sample has a mass of 53.137g?

## Answer:

The density of the alloy pewter is 7.47 g/cm³

**Explanation:**

The density of a substance is calculated by dividing the mass by the volume. In this case:

Given:

Mass = 53.137 g

Volume = 7.11 cm³

Using the formula for density:

Density = Mass / Volume

Substitute the given values:

Density = 53.137 g / 7.11 cm³ = 7.47 g/cm³

Therefore, the density of the alloy pewter is 7.47 g/cm³.
