6 Li + Zn3(PO4)2 ------- > 2 Li3PO4 + 3 Zn




If 48.6 g of zinc is made, how many moles of lithium phosphate are also made? _______ moles

Respuesta :

ardni313

Moles of Lithium phosphate : 0.495

Further explanation

Given

6 Li + Zn₃(PO₄)₂ ------- > 2 Li₃PO₄ + 3 Zn

Required

Moles of Lithium phosphate

Solution

moles of Zinc(Ar=65,38 g/mol) :

= mass : Ar

= 48.6 : 65.38

= 0.743

From equation, mol ratio of Zn :  Li₃PO₄ = 3 : 2, so mol  Li₃PO₄ :

= 2/3 x mol Zn

= 2/3 x 0.743

= 0.495
