Answer:
Explanation:
Hello,
In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:
So we solve for 
by firstly computing the initial pressure:
Finally, we can compute the work by using the following formula:
Best regards.
Answer: The volume of the gold is 
The mass of gold is 19.3 g
The density of gold is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gold = 19.3 grams
To calculate the volume of cube, we use the equation:
where,
V = volume of cube
a = edge of cube
Volume of gold = 
Putting values in above equation, we get:
Putting in the values we get:
Thus density of gold will be
