    We have 379.20grams of zinc present.

    Explanation: The SI base unit for amount of substance is the mole. 1 moles is equal to one moles zinc, or 65.38 grams.

    We can relate the number of moles of zinc to the molar mass of zinc.

    Since 1 mole of zinc = 65.38g/mol

    Number of moles of zinc = mass of zinc / molar mass of zinc

    From the question, number of moles of Zinc is given as 5.8moles We can calculate the mass of zinc present in 5.8 moles as

    5.8moles = mass of zinc / 65.38gmol-1

    When you cross multiply, you have:

    Mass of zinc = 5.8moles*65.38gmol-1

    Mass of zinc = 379.204g

    Therefore the mass of zinc present is 379.20 grams
