Answer to Question #137690 in General Chemistry for bri

Question

What is the mass of a cube of iron that has a volume of 13.5 centimeter³, if the density of iron is 7.87 grams/centimeter³?

Answer 1

iron cube that has a volume, V = 13.5 centimeter³

The density of iron is, D = 7.87 grams/centimeter³

We know, density, D =( M/V )

Or, M = D×V

Puttingthe given values

Mass of iron, M = 7.87 grams/centimeter³ × 13.5 centimeter³

= 106.245 grams

Hence, cube of iron that has a volume of 13.5 centimeter³ has the mass = 106.245 grams
