238 g of uranium contains NA particles =
6.02 x 1023 238 / (6.02 x 1023) g of uranium contains
1 particle therefore 238 x 1014 / (6.02 x 1023)
g of uranium contains 1014 particles = 3.95 x 10-8g of uranium (39.5 ng of Uranium) Just think what a tiny dust particle
that would be…. yet it would contain 1014 uranium atoms! |
