Answer:
P=atm
Explanation:
The problem give you the Van Der Waals equation:
First we are going to solve for P:
Then you should know all the units of each term of the equation, that is:
where atm=atmosphere, L=litters, K=kelvin
Now, you should replace the units in the equation for each value:
Then you should multiply and eliminate the same units which they are dividing each other (Please see the photo below), so you have:
Then operate the fraction subtraction:
P=
And finally you can find the answer:
P=atm
Now solving for b:
Replacing units:
Multiplying and dividing units,(please see the second photo below), we have:
