Question

a block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. it has a mass of 213 g. what is its density? a. 638 g/cm3 b. 6240 g/cm3 c. 0.0773 g/cm3 d. 7.89 g/cm3

Answer 1

Volume = 3 cm × 3cm × 3cm
= 27 cm ³

Mass = 213 g

Density =
`(MASS)/(VOLUME)`

=
`(213 g)/(27 cm ^(3) )`

= 7.89 g / cm³

Thus answer is D.
