How many moles of tungsten atoms are in 6.5x10^25 atoms of tungsten?

a mole contains Avogadro's Number of things

a dozen is 12 , a mole is 6.02E23 (approx)

To find the number of moles of tungsten atoms, we can use Avogadro's number, which states that 1 mole of any substance contains 6.022 x 10^23 particles.

Given that there are 6.5 x 10^25 atoms of tungsten, we can calculate the number of moles as follows:

Number of moles = (Number of atoms) / (Avogadro's number)

Number of moles = 6.5 x 10^25 / 6.022 x 10^23

Number of moles ≈ 10.79

Therefore, there are approximately 10.79 moles of tungsten atoms in 6.5 x 10^25 atoms of tungsten.

To determine the number of moles of tungsten atoms, you need to use Avogadro's number, which represents the number of atoms or molecules in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23.

Here's how you can solve the problem:

1. Identify the given number of tungsten atoms: 6.5x10^25 atoms of tungsten.
2. Divide the given number of atoms by Avogadro's number to convert them into moles. The equation looks like this:

Moles = (Given number of atoms) / (Avogadro's number)

Plugging in the values: Moles = (6.5x10^25 atoms) / (6.022x10^23 atoms/mol)

3. Calculate the result:

Moles = 10.8

So, there are approximately 10.8 moles of tungsten atoms in 6.5x10^25 atoms of tungsten.
