Click on the green heater light on the control panel to turn on the heater and begin heating the water. Make certain the stirrer is on (you should be able to see the shaft rotating). Use the density of water at 25☌ (0.998 g/mL) to determine the mass from the volume and record it in the data table. The molar volume is often used in thermodynamics and liquid-liquid solution contexts, such as when calculating the freezing point depression using the full van't Hoff equation for #K_f# ( "C")/"m"#). 100 mL of water is already in the calorimeter. until you need the " molar density" #barrho = rho/n# of water in mol/L, which is just the molarity #"M"# without the context of a solution, or the molar volume #barV = V/n# in L/mol, which is the reciprocal of the "molar density". Both below and above this temperature, the density of water is lower. The reason I give these 'absurd' concentrations is that what your teachers don't tell you (and this sounds like spam but it isn't!) is that since the concentration of water is so high as pure water, it isn't often discussed. At 25 'C', the density of water is '0.9970749 g/mL', so thats '0.9970749 kg'. The density of water reaches its maximum around 4☌. The percentage degree of dissociation of water at 25 o C is 1.9 × 10 7 and density is 1.0 g c m. mL Water 5 Make certain the stirrer is On (you should be able to see the shaft rotating). Click here:pointup2:to get an answer to your question :writinghand:the degree of dissociation of water at 25 o c is 18times. Use the density of the water to determine the mass of water from the volume and record the volume and mass below.

The density of water at 25☌ is 0.997 g/mL. The calculator below can be used to estimate the density and specific weight of benzene at given temperature (maximum 250☌ or 620 ☏) and maximum 28 bara (400 psia). #"997.0749 g" / ("18.0148 g/mol") = "55.348 mols"# Tabulated values of benzene density specific weight at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures.
