igor_vitrenko [27]

Answer:

0.095 moles of Calcium is there in 5.74 x 1022 atoms of calcium.

Explanation:

  • As we know, 6.023*10^23 atoms of an element is equal to its atomic weight.

       And, 6.023*10^23 atoms of an element is also equal to 1 mole of the             element.

We have,

  • 6.023*10^23 atoms of element calcium equals to 1 mole of Calcium
  • 5.74*10^22 atoms of element calcium equals to

         (1/(6.023*10^.23)) * 5.74*10^22 moles of calcium

Therefore,

  • 5.74 x 1022 atoms of calcium= 0.095 moles of calcium.
