Ms. Moulden’s science class is learning to identify metals by their density. She gave the students a table, shown below, to help
identify their samples. One student’s sample has a volume of 12. 82 cm3 and a mass of 114.61 g. Calculate the density of the sample.
Using the table, what is the identity of the student’s sample?

Answer:
The final volume is 1.6 L.
Explanation:
It is given that,
A diver has a lung capacity of 2.4 L when the pressure is 0.8 atm. We need to find the volume of the diver’s lungs when the pressure changes to 1.2 atm. Let V₂ is volume.
It is based on Boyle's law. According to this law,
K is constant
So, the final volume is 1.6 L.
