MCQ
How many grams of $Ca{C_2}{O_4}$ (molecular weight $= 128$) on dissolving in distilled water will give a saturated solution $[{K_{sp}}(Ca{C_2}{O_4}) = 2.5 \times {10^{ - 9}}$ $mo{l^2}{l^{ - 2}}]$
- ✓$0.0064$
- B$0.1280$
- C$0.0128$
- D$1.2800$
$ = 5 \times {10^{ - 5}}\,mol{L^{ - 1}}$
$ = 5 \times {10^{ - 5}} \times 128 = 640 \times {10^{ - 5}}$$ = 0.0064\,g$
