96. Strictly speaking, the solvent is the component of a solution that is present in the largest amount on a mole basis. For solutions involving water, water is almost always the solvent because there tend o be many more water molecules present than molecules of any conceivable solute. To see why this is so, calculate the number of moles of water present in 1.0 L of water. Recall that the density of water is very nearly 1.0 g/mL under most conditions.
Interpretation:
The number of moles of water present in
Concept Introduction:
Solution is composed of solute and solvent particles. Solute particles are always present in lower amount as compared to amount of the solvent in the solution.
The atomic mass of an element is defined as the sum of number of protons and number of neutrons. Molar mass of an element is determined from atomic mass of an element.
The number of moles is calculated by the formula,
The volume and density of water is given to be
The mass of water is calculated by the formula,
Substitute the values of volume and density in the equation (1).
The molar mass of water is
