Question

1. using the data table to the right, determine the identity of a cube of metal that has a volume of 1.73 cm³ and a mass of 33.3 grams.

a. gold
b. nickel
c. silver
d. zinc

name of metal\tmelting point (°c)\tdensity (g/cm³)
gold\t1,064.18\t19.282
silver\t961.78\t10.501
copper\t1,084.62\t8.96
nickel\t1,455\t8.912
zinc\t419.53\t7.134

1. which of the following is not an example of a physical

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Calculate density of the metal

Given $m = 33.3$ grams and $V=1.73\ cm^{3}$, then $
ho=\frac{33.3}{1.73}\ g/cm^{3}\approx19.25\ g/cm^{3}$.

Step3: Compare with table values

From the table, the density of gold is $19.282\ g/cm^{3}$, which is closest to the calculated density.

Answer:

A. Gold
