If the density is 1.0 g/ml, one liter of the solution will weigh 1000 grams. 3.0 % of this mass or 30 grams of it is constituted of H2O2. The molar mass of H2O2 is 2 (1.008 + 15.999) = 34.014. The molarity of this solution is therefore 30/34.014 = 0.88, to the justified number of significant digits.

1% solution of KOH contains 1g of KOH in 100g of solution. This means that you need to mix 1g of KOH and 99g of water.
an aqueous solution of copper sulphate is homogeneous
The molarity is 0,031.

buffer solution
the solution itself, yes. it must contain water to be called an aqueous solution. the term aqueous designates water as the solvent/diluent.
Water (H2O) is two atoms of hydrogen and one of oxygen.
A base
This solution is called water solution or aqueous solution.
We can not answer this question with out more " the following".
1.00 * 10^-14/ 0.34 = 2.9^-14 M or (3.2e-14 M)
