Answer:
<h3>The answer is 10 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 300 g
volume = final volume of water - initial volume of water
volume = 40 - 10 = 30 mL
We have
We have the final answer as
<h3>10 g/mL</h3>

Answer:
Option D is correct.
Explanation:
Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure because any gas at a higher temperature and a lower pressure will behaves like an ideal gas. for eg.
nitrogen at STP show its behavior as an ideal gas.
When pressure of a gas increased & temperature is decreased then the gas does not follow ideal gas law.
Therefore option D is correct.
