Concept Introduction:
The relationship between density, volume, and mass is as:
Here,
Density is defined as the ratio of mass of the sample to its volume. It is generally expressed in
Answer to Problem 1KSP
Correct answer:
The volume of the given gold nugget is
Explanation of Solution
Reason for correct option:
Use equation (1) to calculate the density of the gold nugget as follows:
Now, rearrange equation (1) so that the volume of the gold nugget is calculated as:
Substitute,
Hence, option (d) is correct.
Reasons for incorrect options:
Option (a) is incorrect because according to the above calculation, the value
Option (b) is incorrect because according to the above calculation, the value
Option (c) is incorrect because according to the above calculation, the value
Option (e) is incorrect because according to the above calculation, the value
Hence, options ( a), (b), (c), and (e) are incorrect.
