Answer:
<h3>The answer is 200 cm³</h3>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 150 g
density = 0.75 g/cm³
We have
We have the final answer as
<h3>200 cm³</h3>Hope this helps you
Explanation:
According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature and moles.
Mathematically, P =
where, k = proportionality constant
Also, formula for initial pressure and volume is as follows.
or,
=
= 30 atm L
Now, we will calculate the value of as follows.
=
= 30 atm L
Hence, as this means that it signifies that gas obeys boyle's law.
