Also, R is a gas constant. It's always constant. And now I plug in N total or the total number of molecules in my system. Now I can go to the next step. And instead of writing N total, I plug in all these three guides or the addition of these three guides and I get in parentheses n one plus n two plus n three times RT divided by V.
And now I need simple algebra to distribute to each guide. And I get n one R T over V plus n two r T over V plus n three r T over V. And we see using the ideal gas law that we get the same exact thing as up here.
