Question #15295

The density of iron is 7.87g/ml. What is the mass of a 5.00cmx4.00cmx1.00cm block of iron?

Expert's answer

The volume of a block is

V = 5.00[cm]x4.00[cm]x1.00[cm] = 20.00 cm³.

Taking into account that 1[ml] = 1[cm³], we have that the mass of a block is

M = 7.87[g/cm³]*20.00[cm³] = 157.40 g.

V = 5.00[cm]x4.00[cm]x1.00[cm] = 20.00 cm³.

Taking into account that 1[ml] = 1[cm³], we have that the mass of a block is

M = 7.87[g/cm³]*20.00[cm³] = 157.40 g.
