Question

an object has a mass of 26.94 grams and a volume of 2.568 cubic centimeters. what material is it likely to be made of?
substance | iron | gold | silver | copper
density (g/cm³) | 7.874 | 19.32 | 10.49 | 8.92
options:
a) copper
b) gold
c) iron
d) silver

Explanation:

Step1: Recall the density formula

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

Step2: Substitute the given values

We know that $m = 26.94$ grams and $V = 2.568$ cubic centimeters. Substitute these values into the formula: $
ho=\frac{26.94}{2.568}$.

Step3: Calculate the density

Perform the division: $\frac{26.94}{2.568} = 10.49$ grams per cubic centimeter.

Step4: Compare with the given densities

Looking at the table, the density of silver is $10.49$ $g/cm^3$, which matches our calculated density.

Answer:

D) silver
