1. A gram of hydrogen contains 6 x 10^18 protons. How many Protons are in 500 grams of hydrogen ?
Thank you ! :)
500 x 6 x 10^18 = 3000 x 10^18 = 3 x 10^21
6 x 10^18 X 500=3.0 X 10^21 protons. By the way, 1 mole of Hydrogen contains 6 X 10^23 protons or atoms(That's Avogadro's Number). Whoever gave you that number, it's incorrect. You can check here:
