The number of moles of magnesium that are in the strip is 0.25 mole
From the question:
We are to determine number of moles of magnesium that are present in the strip
Using the formula
[tex]Number\ of\ moles = \frac{Mass}{Atomic\ mass}[/tex]
Mass of magnesium strip = 6.10 g
Atomic mass of magnesium = 24.305 g/mol
∴ Number moles of magnesium present = [tex]\frac{6.10}{24.305}[/tex]
Number moles of magnesium present = 0.250977 mole
Number moles of magnesium present ≅ 0.25 mole
Hence, the number of moles of magnesium that are in the strip is 0.25 mole.
