How many grams of CaC_(2)O_(4) (molecular weight = 128) on dissolving water will give a saturated solution [K_(sp)(CaC_(2)O_(4)) = 2.5 xx 10^(-9) mol^(2) I^(-2)]

Answer»

`0.0064 G`
`0.1280g`
`0.0128 g`
`1.2800 g`

Solution :Solubility of `CaC_(2)O_(4) = sqrt(K_(sp)) = sqrt(2.5 XX 10^(-9))`
`= 5 xx 10^(-5) mol L^(-1)`
`= 5 xx 10^(-5) xx 128 = 640 xx 10^(-5) = 0.0064 g`.
