Answer to Question #12162 in Other Chemistry for Amal
find the number of oxygen atoms in 4 grams of O2
Oxygen in the form O2 has a molar mass of 31.9988 g mol^-1. In 4 grams there will be 4/31.9988 mol = 0.1250 mol. One mole of O2 equals 6.022 x 10^23 molecules of oxygen, and thereby 7.53 x 10^22 molecules of O2 in 4 gram. Since O2 is diatomic there are twice as many atoms as there are molecules and the final calculation to determine the number if atoms is 7.53 x 10^22 * 2 = 15.06 x 10^22 atoms of oxygen.
I have no more assignments.
Thank you for all the help! With 19 credit hours, their is always one class that hits the back burner, with your help i was able to get a B in this class and am going to Walk on graduation.
