Problem: (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?
FREE Expert Solution
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:
