Explanation:
Moles of zinc present in the sample that have a mass of 65.2 g are 0.997 moles.
Moles are used to calculate the amount of substance to measure the small entity. It is calculated as:
[tex]\rm moles = \rm \dfrac{mass}{molar\; mass}[/tex]
Given,
Molar mass of zinc = 65.39 g/mol
Mass of zinc = 65.2 g
Moles are calculated as:
65.2/65.39 = 0.997 moles
Therefore, 0.997 moles of zinc are present.
