Question

Name Melting Point Density (g/cm3)

Zinc 419.53 oC 7.134
Nickel 1455oC 8.912
Copper 1084.62oC 8.96
Silver 961.78oC 10.501
Gold 1064.18oC 19.282


Based from the table,Determine the identity of a cube of metal that measures 1.5 cm on each side and has a mass of 35.45g.
A) Gold
B) Nickel
C) Silver
D) Zinc

Answer 1

Silver

Step-by-step explanation:

Based on the density calculation, the cube must be made of silver. To determine the density, divide the mass by the volume. The volume = l x w x h. Since this is a cube, this must be silver according to the chart.

Answer 2

Volume of cube = l³
= 1.5³
= 3.375 cm³
Density = mass / volume
= 35.45 / 3.375
= 10.504
Comparing to the quoted values, the material of the cube is most likely to be silver since their densities are similar.
The answer is C
