$$10 \mathrm { mL } , 30 \mathrm { mL }$$  and  $$60\mathrm { mL }$$  of three liquids are mixed together. What is the concentration in volume percent of the solutes ?

Solubility of NaOH in water:

The equilibrium constant for the following equilibrium is given at $$0^0C$$:

The relative lowering of vapour pressure of a solution of $$6g$$ of urea in $$90g$$ of water is equal to.

When metal 'M' is treated with $$NaOH$$, a white gelatinous precipitate 'X' is obtained, which is soluble in excess of $$NaOH$$. Compound 'X' when heated strongly gives an oxide which is used in chromatography as an adsorbent. The metal 'M' is:
