Question

How many moles of atoms are present in 3 moles of Ca(NO3)2
moles.

Answer 1

Answer: In 3 moles of Ca(NO3)2, there are 24 moles of atoms.

Explanation: This is because:

1 mole of Ca(NO3)2 contains 1 mole of calcium (Ca), which has 1 mole of atoms

1 mole of Ca(NO3)2 contains 2 moles of nitrate (NO3), which has 6 moles of atoms

So in total, 1 mole of Ca(NO3)2 contains 1 + 6 x 2 = 13 moles of atoms.

Therefore, 3 moles of Ca(NO3)2 contains 3 x 13 = 39 moles of atoms.
