Achemist has a jar containing 388.3 g of iron filings. how many moles of iron does the
jar contain?

6.94 mol

Explanation:

Data given:

Mass of iron filings (Fe) = 388.3 g

no. of moles of iron (Fe) = ?

Solution:

For this formula will be used

       no. of moles = Mass in grams/ molar mass

molar mass of Fe = 56 g/mol

Put values in equation

                no. of moles = 388.3 g / 56 g/mol

                no. of moles = 6.94 mol

So,

no. of moles of iron in jar = 6.94 mol
