WebOct 6, 2024 · I'm doing a lab where I am supposed to calculate the "molarity of water" in pure water at 30 degrees Celsius. With the hint that the density of water at 30 degrees Celsius is 0.9957 g/mL. What is the molarity? WebAlso, the molarity of pure water can be found using the density of pure water which is 1 g/ml. As molarity is calculated through the use of litres as a unit, hence the conversion to litres is required. Thus, Density=1g/ml = 1*1000g/L= 1000g/L Now we obtain the mass or weight of pure water to be 1000g.
