Question

26.8 moles of argon contain how many atoms?

Answer 1

1.61 × 1023 Multiply by 26.8 to get the answer.161.33 x 10 ^23  

Answer 2

Answer : The number of atoms of argon are $1.61\times 10^{25}$

Explanation : Given,

Moles of argon = 26.8 moles

As we know that,

1 mole of substance always contains $6.022\times 10^{23}$ number of atoms.

As, 1 mole of argon contains $6.022\times 10^{23}$ number of atoms

So, 26.8 mole of argon contains $26.8\times 6.022\times 10^{23}=1.61\times 10^{25}$ number of atoms.

Therefore, the number of atoms of argon are $1.61\times 10^{25}$
