The reaction between lithium sulfate and potassium phosphate is a a double displacement reaction. This reaction can be written as:
`3 Li_2SO_4 + 2 K_3PO_4 -> 2 Li_3PO_4 +3 K_2SO_4`
In this well-balanced chemical reaction, we can see that lithium replace potassium and vice-versa and hence this is a double displacement reaction.
Molar masses of lithium sulfate = 2 x 7 + 32 + 4 x 16 = 110 g/mol
Molar mass of lithium phosphate...
The reaction between lithium sulfate and potassium phosphate is a a double displacement reaction. This reaction can be written as:
`3 Li_2SO_4 + 2 K_3PO_4 -> 2 Li_3PO_4 +3 K_2SO_4`
In this well-balanced chemical reaction, we can see that lithium replace potassium and vice-versa and hence this is a double displacement reaction.
Molar masses of lithium sulfate = 2 x 7 + 32 + 4 x 16 = 110 g/mol
Molar mass of lithium phosphate = 3 x 7 + 31 + 4 x 16 = 116 g/mol
Using stoichiometry:
3 moles of lithium sulfate produces 2 moles of lithium phosphate,
or, 3 x 110 g lithium sulfate produces 2 x 116 g lithium phosphate
or, 10.3 g lithium sulfate produces (2 x 116) x 10.3 / (3 x 110)
= 7.24 g.
Thus, 10.3 g of lithium sulfate will produce 7.24 g lithium phosphate.
Hope this helps.
