How many oxygen atoms are in 225g O2
1 answer:
Answer:
8.468 x 10^24.
Explanation:
We know from Avogadro’s Law that 1 mol of a gas contains 6.022 x 10^23 molecules.
So, 7.031 mol contains 7.031 x 6.022 x 10^23 = 4.234 x 10^24 molecules. Since oxygen is diatomic, the number of oxygen atoms is 8.468 x 10^24.
