First you need to find the Atomic Mass of magnesium, 24.3 grams.
Then you can do a simple conversion:
Grams ÷ Atomic mass = Moles
7.5 grams ÷ 24.3 grams = 0.309 moles Mg

∙ 12y agoOne mole equals 6.02 x 10 raised to the power 23 units of anything. In other words, 1 mole is simply the number 6.02 x 10 raised to the power 23. Therefore, the number of atoms in 3.2 moles of magnesium is computed as follows:
3.2 x 6.02 x 10 raised to the power 23

∙ 10y ago1 mole of Mg contains 6.02 x 1023 Mg atoms.
Accordingly, 7.21 moles of Mg contains 7.21 x 6.02 x 1023 = 4.34 x 1024 Mg atoms.

How many atoms will be present in0.05mole of ozone?
0.05 moles O3 (6.022 X 1023/1 mole O3) = 3.01 X 1022 atoms of ozone ======================
How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen Here is the formula 2 Mg plus O 2 is equal to 2 Mg O?
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
How many atoms are in 2.5 moles of Mg with steps?
1 mole of any element contain 6,022 140 857.1023 atoms (Avogadro number).2,5 moles of magnesium contain 15,0553521425.1023.
