Question

How much copper is present in a cube that measures 3.20cm on each side, if the density of copper is 8.96 g/mL

Answer 1

Answer:

290.32 g

Explanation:

First we calculate the volume of the cube:

• Volume = (3.20 cm)³ = 32.768 cm³

Now we convert cubic centimeters to mililiters:

• 32.768 cm³ * 1 mL / 1 cm³ = 32.768 mL

Finally we calculate the mass, using the equation for density:

• Density = mass / Volume

• mass = Density * Volume

• mass = 8.86 g/mL * 32.768 mL = 290.32 g
