Answer:
Step-by-step explanation:
To calculate the number of moles of magnesium in 0.1 g of magnesium, we first need to determine the molar mass of magnesium. The molar mass of magnesium is 24.31 g/mol.
Using this information, we can use the following formula to calculate the number of moles of magnesium:
moles of magnesium = mass of magnesium / molar mass of magnesium
moles of magnesium = 0.1 g / 24.31 g/mol
moles of magnesium ≈ 0.00412 mol
Therefore, there are approximately 0.00412 moles of magnesium in 0.1 g of magnesium.
