Density and molarity
WebNext, multiply the volume in milliliters by the density of hexane to find the mass: mass = density x volume. mass = 0.6594 g/mL x 9,220 mL. mass = 6,062.948 g. So, 9.22 x … WebThe relationship between molarity, moles and volume are shown below. where M = molarity (M or mol/L), n = number of moles (mol) and v = volume (L). Step 1: Determine which formula to use. We were given the number of moles of the substance and the volume of solvent used. We do not know the concentration in molarity.
