Question

How many moles are in 0.1 g of Magnesium?

Answer 1

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.

Answer 2

there are approximately 0.004118 moles in 0.1 g of magnesium.

Step-by-step explanation:

The molar mass of magnesium is approximately 24.31 g/mol. To calculate the number of moles in 0.1 g of magnesium, we can use the following formula:

Number of moles = Mass / Molar mass

Number of moles = 0.1 g / 24.31 g/mol

Number of moles = 0.004118 mol (rounded to 3 significant figures)

Therefore, there are approximately 0.004118 moles in 0.1 g of magnesium.
