how many moles does. 24g of magnesium contain
Answers
Mg=24g
GAM Of Mg =24g
therefore 24g =1 mol
Answer: The correct answer will be 0.988 moles.
Explanation: To determine the number of moles in 24g of magnesium, we need to divide the mass of magnesium by its molar mass.
The molar mass of magnesium (Mg) is approximately 24.31 g/mol.
So, the number of moles of magnesium in 24g can be calculated as:
- 24 g Mg / 24.31 g/mol = 0.988 mol Mg
Therefore, 24g of magnesium contains approximately 0.988 moles of magnesium.
This calculation is based on the definition of a mole as the amount of substance that contains the same number of particles (atoms, molecules, etc.) as there are in 12 grams of carbon-12, which is approximately 6.022 x 10^23 particles (Avogadro's number).
The alkaline earth series contains the silvery-white element magnesium. Since it burns with a brilliant white flame and has an atomic number of 12, it is utilised to create strong lightweight alloys and is also used in flash bulbs and pyrotechnics.
