Is entropy of water is higher than entropy of ice?
Entropy of water is higher than ice due randomness in the water molecule
What type of solution has the highest concentration of water molecules?
That is what is known as an aqueous solution.
Which of the following is a mixture but not a solution?
We need to know what 'the following' are to answer the question!
How does the entropy of a system change for condensation of water?
The entropy is lower.
Entropy change for dissolving salt in water?
This question isn't very complete, but if you meant what is the solute or solvent, the water would be the solvent because there is more water than salt. In this case, the salt is the solute. If there...

It increases
What is the major force that drives nonpolar substances out of aqueous solution?
Increased entropy of solvent water molecules.

Why NaCl is very soluble but not CaO is only slightly soluble in water?
Its all to do with enthlapy and entropy. Anything which is soluble usually has a negative standard enthlapy of solution - the energy involved when 1 mole of solute dissolves in a solvent to give an infinately dilute solution. However, NaCl has a slightly positive enthalpy of solution, yet it dissolves. The reason for this is entropy - the change in the amount of disorder. When NaCl dissolves in solution, there is more chaos, more molecules within the solution. Any process that has a large positive entropy change will be favourable - spontaneous and can occur (reaction will 'go'). However, with CaO, the Ca2+ formed in solution has a high affinity (attraction to) for water molecules, hence a lot of water molecules are arranged orderly - less chaos and hence a negative entropy. This should in effect make the compound insoluble, however, the slight solubility is due to it still having a negative enthalpy change of solution - hence despite entropy it is still slightly soluble. (You may be asking how is dissolving CaO possible if entropy is negative? The entropy of the system maybe negative, but the entropy of the surroundings is positive (dissolving gives out heat - exothermic), hence the overall entropy (sum of both entropies) is positive and the reaction will 'go'.

If water H2O is polar and oxygen O2 non-polar how can there be dissolved oxygen in water?
The simple answer is that most everything happens at least a little bit. The reason why is EQUILIBRIUM. You are correct---water is polar and oxygen is non-polar. The water molecules have great hydrogen bonding and dipole-dipole interactions with each other that the oxygen molecules cannot replace, and so it will take energy or ENTHALPY for oxygen to mix its way into the water. So the process is ENDOTHERMIC and hence unfavorable. However, when you dissolve oxygen in water, you get disorder---something that scientists quantify by talking about a solution's ENTROPY. It is favorable for entropy to increase, and in this case the entropy of the water solution would go up if you were to be able to squeeze some water molecules in there. So entropy and enthalpy are at odds for this reaction. Enthalpy is unfavorable, entropy is favorable. In situations like that systems will reach a state of equilibrium in which the reaction partially occurs. How much will depend on the relative sizes of the entropy and enthalpy changes.
