Part A. We’re being asked to determine the mass (in grams) of 6.02 x 1023 hydrogen atoms.
We are given:
6.02 x 1023 hydrogen atoms
1 H atom = 1.67 x 10-24 g
Calculate the atomic mass of H:
(a) If the average mass of a single hydrogen atom is 1.67 x 10-24 g, what is the mass in grams of 6.02 x 1023 hydrogen atoms? How does your answer compare numerically with the atomic mass of hydrogen?
(b) If the average mass of a single oxygen atom is 26.558 x 10-24 g, what is the mass in grams of 6.02 x 1023 oxygen atoms? How does your answer compare numerically with the atomic mass of oxygen?
