Question

Сколько атомов металла магния содержится в 3 молях вещества?

Answer 1

Так как атомная масса магния = 24, мы должны 24 умножить на 3 = 72

Answer 2

Calculating the Number of Atoms of Magnesium in 3 Moles

To calculate the number of atoms of magnesium in 3 moles of the substance, we can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole.

Avogadro's number is approximately 6.022 x 10^23 atoms per mole.

Now, let's calculate the number of atoms of magnesium in 3 moles of the substance.

Using Avogadro's number: - 1 mole of any substance contains approximately 6.022 x 10^23 atoms. - Therefore, 3 moles of the substance would contain approximately 3 * 6.022 x 10^23 atoms.

So, 3 moles of the substance contain approximately 1.8066 x 10^24 atoms.

This calculation is based on the concept of Avogadro's number, which states the number of atoms, ions, or molecules in one mole of a substance.
