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

Two objects of the same mass are moving at the same velocity. You give
vladimir1956 [14]
I would imagine they’d be equal.
F = ma
We can treat mass and force as constants because they do not change throughout both systems and they are the same on both systems. That would mean the acceleration would be the same for both systems.

An explanation of this could be the two forces are acting in different directions, so one is positively accelerating the object and the other is negatively accelerating it
