In science, whenever we need to convert between the moles of a chemical compound into the mass of the chemical compound, we use the mole formula which is given as {eq}\text{ Moles}=\dfrac{\text{ Mass}}{\text{ Molar mass}} {/eq}....
Calculate the molality of the solution. Molality:Molality is defined as the amount of solute in moles, present per kilogram of solvent in a solution. Molality is similar in name to molarity, which is defined as the moles of solute present per liter of the solutio...
