How many moles of solute particles are present in one litre of10^(-4 )

1.	How many moles of solute particles are present in one litre of10^(-4 )M potassium sulphate ?
Answer» Solution :In `10 ^(-4)M K _(2) SO _(4)` solution, there are `10 ^(-4)` moles of potassium sulphate. `K _(2)SO _(4)` molecule contains 3 ions `(2 K ^(+) and 1 SO _(4) ^(2-))` 1 MOLE of `K _(2) SO _(4)` contains `3 XX 6. 023 xx 10 ^(23)` ions `10 ^(4) ` mole of `K _(2) SO _(4)` contaisn `3 xx 6.023 xx 10 ^(23) xx 10 ^(-4) ` ions `= 18.069 xx 10 ^(19)`
