How Big is Avogadro’s Number?
In this discussion, you will do a calculation using Avogadro’s number, 6.02 × 1023, or 1 mole. Think of an everyday item and either do a google search to see what it’s mass is or else measure it’s mass yourself. Next, multiply that mass by Avogadro’s number to determine how much 1 mole of that item would weigh. Report your result in both scientific notation and as an ordinary number.
For example, 1 m&m candy weighs about 0.88 g
0.88 g × 6.02 × 1023 = 5.3 × 1023 g = 530,000,000,000,000,000,000,000 g
1 m&m = 0.88 g
1 mole m&m = 5.3 × 1023 g or 530,000,000,000,000,000,000,000 g
