Water<span> can </span>dissolve salt<span> because the positive part of </span>water<span> molecules attracts the negative chloride ions and the negative part of </span>water<span> molecules attracts the positive sodium ions. The amount of a substance that can </span>dissolve<span> in a liquid (at a particular temperature) is called the solubility of the substance. So the solute is the salt and the solvent is the water. I believe that is correct.</span>
Given k=100, Area if plate A = 1.00 cm2

Thickness of rutile 

Without any dielectric medium capacitance of a parallel plate capacitor is c = oAd
When a dielectric is placed between capacitors plates then capacitance c1 = KoAd

B is the answer to your question
B.a homogeneous mixture
A solution is a homogeneous mixture of two or more substances. The amount of solute that can be dissolved in solvent is called its solubility.
