Answer 1

4.3 g

Step-by-step explanation:

Step 1: Given data

Volume of the piece of Pb: 3.0 mL

Step 2: Calculate the mass of the piece of Pb

The density of Pb is 11.35 g/mL.

3.0 mL × 11.35 g/mL = 34 g

We will look for the volume of a piece of Fe with a mass of 34 g.

Step 3: Calculate the volume of a piece of 34 g of Fe

The density of Fe is 7.87 g/mL.

34 g × 1 mL/7.87 g = 4.3 g
