(b) How many bromine atoms are present in one mole of 79Br?

Question

Accepted Answer

Hi everyone here we have a question asking us to calculate the number of oxygen atoms in one mole of 02. So we're going to start out with our one mole of 02 And we're going to multiply that by two moles of oxygen because there are two moles of oxygen in over one more of 02. And we're going to multiply that by avocados number so 6.0-2 Times 10 to the 23rd oxygen atoms over one mole of oxygen and our moles of 02 are canceling out, our moles of oxygen are canceling out, leaving us with oxygen atoms And that equals 1.20 Times 10 to the 24th oxygen atoms. And that is our final answer. Thank you for watching. Bye.
