What mass of AI2O3 forms, knowing the molar mass of Al2O3 is 102 g/mol ?
TiliK225 [7]

Question

What mass of Al₂O₃ form is produced if 25.00 g of aluminum (al) is reacted completely?, knowing the molar mass of Al₂O₃ is 102 g/mol?

Atomic mass of Al =27 and O = 16

The molar mass of Al₂O₃ = 102.

Mass of aluminium in 102 g of Al₂O₃ = 54 g

54 g Al => 102 g Al₂O₃

25g Al => x g Al₂O₃

x = 25*102/54 = 47.2 g Al₂O₃

Why doesn't the reaction Pb+Zn(C2H3O2)2--> Zn + Pb(C2H3O2)2 occur?
Komok [63]
Because zinc is above lead on the activity series. This means that in a single displacement reaction such as this one, Pb will not easily displace Zn.

Answer the following stoichiometry question:
labwork [276]

Answer:

Mass = 684.2 g

Explanation:

Given data:

Moles of Aluminium = 25.36 mol

Mass of Al = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Mass = number of moles × molar mass

Molar mass of Aluminium = 27 g/mol

Now we will put the values:

Mass = 25.36 mol × 26.98 g/mol

Mass = 684.2 g
