Answer:
107.649g
Explanation:
To calculate mole
Formulae is
Mole=mass/mass number
Now our parameters are
Mole=3.987mol
Mass number if AL= 27g/mol
Mass=?
You make mass your subject formula
Mass=mole x molar mass
Insert you parameters
Mass= 3.987mol x 27g/mol
Mole will cancel mole
3.987 will multiply 27
Final answer 107.649g
Answer:
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
