Explanation:
mole = mass in g/ molecular weight
molecular weight of Al2O3 =2(13) + 3(16) =74g/mol
reacting mass = 27 g
mole = 27/74 = 0.36mol
The branch of science which deals with chemicals and their nature is called chemistry.
The correct answer for the question is mole 0.36 moles
The formula we will use to solve the equation is as follows:-
[tex]n= \frac{mass}{molecular\ weight}[/tex]
The molecular weight of [tex]Al_2O_3[/tex] =[tex]2(13) + 3(16) =74g[/tex]
The mass of the compound is =27 g.
After solving the equation we will get.
[tex]mole = \frac{27}{74} = 0.36mol[/tex]
Hence, the correct answer is 0.36.
