Vedclass · Answer

(C) The density of pure water is approximately $1000 \ g/L$ at $298 \ K$. The molar mass of water $(H_2O)$ is $18.02 \ g/mol$. Molarity $(M)$ is defined as the number of moles of solute per liter of solution. $M = \frac{	ext{mass}}{	ext{molar mass} 	imes 	ext{volume in liters}} = \frac{1000 \ g}{18.02 \ g/mol 	imes 1 \ L} \approx 55.55 \ mol/L$. Therefore,the molarity of pure water is approximately $55.6 \ M$.
