Sagot :
7.8049856 g of aluminium phosphate is produced from 7.5 g of lithium phosphate in this balanced equation.
What are moles?
A mole is defined as 6.02214076 × [tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
[tex]2Li_3PO_4 + Al_2(SO_4)_3[/tex]→ [tex]3Li_2SO_4 + 2AlPO_4[/tex]
Moles of 7.5 g of lithium phosphate.
The molar mass of lithium phosphate is 115.79 g/mol.
Moles = [tex]\frac{mass}{molar \;mass}[/tex]
Moles =[tex]\frac{7.5 g}{115.79 g/mol}[/tex]
Moles = [tex]\frac{7.5 g}{115.79 g/mol}[/tex]
Moles = 0.06477243285
Now we will compare the moles of [tex]AlPO_4[/tex] with [tex]Li_3PO_4[/tex].
[tex]Li_3PO_4[/tex] : [tex]AlPO_4[/tex]
2 : 2
0.385 : 2÷2× 0.064 = 0.064 mol
Mass of [tex]AlPO_4[/tex] :
Mass of [tex]AlPO_4[/tex] = moles × molar mass
Mass of [tex]AlPO_4[/tex] =0.064 mol × 121.9529 g/mol
Mass of [tex]AlPO_4[/tex] = 7.8049856 g
Hence, 7.8049856 g of aluminium phosphate is produced from 7.5 g of lithium phosphate in this balanced equation.
