If a mixture is 4.6 g of water and .5 g of copper chloride ,what is the percent composition of water?

The percent composition of water : 90.2%

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

mass of water = 4.6 g

mass of Copper chloride = 0.5 g

mass of solution :

So the percent composition of water (%mass) :

that tool would be a compass
