How many molecules of N₂O₄ are in 8.016 kg N₂O₄? The molar mass of N₂O₄ is 92.02 g/mol?

Answer 1

8016 grams / (92.02 grams/mol) =>

(8016/92.02) mol

There are 6.02 * 10^23 molecules in a mol

(8016/92.02) * 6.02 * 10^23 =>

(8016 * 602 / 9202) * 10^23 =>

524.41121495327102803738317757009.... * 10^23 =>

5.244 * 100 * 10^23 =>

5.244 * 10^25
