What is the density of a sample of the alloy pewter, (a mixture of tin and copper or lead) if a 7.11 cm3 sample has a mass of 53
xxTIMURxx [149]

Answer:

<h3>The answer is 7.47 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 53.137 g

volume = 7.11 cm³

We have

density =  \frac{53.137}{7.11}  \\  = 7.473558368...

We have the final answer as

<h3>7.47 g/cm³</h3>

Hope this helps you
