We know that in 1 mole there is Avogadro’s number of atoms(no matter of what kind of mole) 6.02 x 10^23.
In order to find the number of moles we just apply the rule of three.
1 mole.............. 6.02 x 10^23.
x mole..............<span>6.02 x 10^25
x = </span>6.02 x 10^25/6.02 x 10^23. = 10^2 = 100 moles
Answer:
the second one is the correct answer
