Explanation:
Detailed explanation-1: -We know that 1 mole of any substance contains 6.023 into 10 to the power 23 number of atoms or molecules. Hence, in 4 moles of magnesium we will have 2.4092 into 10 to the power 24 atoms of magnesium, so the number of magnesium atoms present in 96 unit masses 2.4092, any 4.
Detailed explanation-2: -Answer and Explanation: There are 2.409 X 1024 atoms of magnesium in a sample of 4 moles of magnesium. Using Avogadro’s number, we know that there are 6.022 X 1023 atoms in every mole of our sample.
Detailed explanation-3: -Number of atoms of Mg = Moles×Avogadro number = 2×6. 023×1023=12.
Detailed explanation-4: -Hence the Magnesium will contain 24.08 × 10²³ atoms.
