Question

A chemist has a jar containing 388.2 g of iron filings. How many moles of iron does the jar contain?

Answer 1

Thank you for getting in touch with us for the answer of your query. In order to find the number of moles, we need to know the mass and molar mass of the element, and the formula is:
Number of moles = Mass (g) / Molar Mass
Mass = 388.2
Molar Mass of Iron = 56
Moles of Iron = 388.2 / 56 = 6.93
I hope this answer will be helpful for you.
