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* 10^(25)`

Explanation : Given,

Moles of argon = 26.8 moles

As we know that,

1 mole of substance always contains
`6.022* 10^(23)` number of atoms.

As, 1 mole of argon contains
`6.022* 10^(23)` number of atoms

So, 26.8 mole of argon contains
`26.8* 6.022* 10^(23)=1.61* 10^(25)` number of atoms.

Therefore, the number of atoms of argon are
`1.61* 10^(25)`
