Question

The density of pure iron is 7.874 g/cm³. What is the mass (in grams) of a piece of iron with a volume of 20.00 cm³?

Answer 1

157.48 g

Step-by-step explanation:

To calculate the mass of a piece of iron with a volume of 20.00 cm³, we can use the formula:

mass = density x volume

where density is the density of pure iron (7.874 g/cm³) and volume is the volume of the iron piece (20.00 cm³).

mass = 7.874 g/cm³ x 20.00 cm³ = 157.48 g

So, the mass of the iron piece is 157.48 g.
