How many potassium atoms are in 250.0 grams of potassium?
loris [4]

Hi!


The correct option would be 3.85x10^(24)


To find the number of atoms in 250g of potassium, we need to first calculate the number of atoms in


1 mole of Potassium = 39g which contains 6.022x10^(23) atoms of K

<em>(Avogadro's constant value for the amount of molecules/atoms in one mole of any substance)</em>

<em>Solution</em>

So as 39g of Potassium contains 6.022x10^(23) K atoms

1g of Potassium would contain 6.022x10^(23) / 39 = 1.544 x10^(22) atoms

So 250g of Potassium would contain 1.544x10^(22) x 250 = 3.86x10^(24) atoms
