What is the mass of 3.987 mole of AL?

107.649g

Explanation:

Mass of a substance = number of moles of the substance times molar mass of the substance

Here, the substance is aluminum, Al.

Number of moles given= 3.987mol

Molar mass of Al = 27g/mol

Therefore,

Mass of Al = 3.987mol X 27g/mol

= 107.649g
