How many atoms are in 0.75 moles of neptunium?

This is a test run on Lee. A test run. Do I hate this?

To start this problem. Let's identify what we know and what we want. What we know is that we have 7.85 times 10 to the 23rd Adams of potassium. And what do we want we want? How many moles is this? So let's start with what we know. We know that we have 7.8 five times 10 to the 20 three Adams of potassium. And we're looking right now at the units of Adams and Moles. Do we know of a number that maybe was taught in class that uses both Adams and moles in the units we dio? We know that all the God rose number is 6.22 times turn to the 23rd. Adams Permal. This is a very good number to use when converting between Adams and moles or moles toe Adams. So let's see if we want to get moles. We need to cancel out Adams. So that means that we would have to divide 7.85 times 10 to the 23 by all the Dodgers number 6.2 to times 10 to the 23 Adams her that cancels out Adams and leaves us with moles because since it's on the bottom of a fraction on the bottom of a fraction, it bounces it up to the dinner, the numerator. So I plug this number into my calculator because I can't divide this in my head, and I got an answer of 1.3. So Euro Morel's of potassium and I'm going to circle our final answer right here. This is good because it has the same number of sig figs as the variables that were given in the original problem.

Please. Today I'll be going over Chapter six. Question number three, which talks about Adams in a law. Radames. So one more. I used to find that his avocados number, which in 6.0 to 2 times 10 to 20 bird that does.
