The density of air at NTP is 1.205 kg/m 3. The density of the solution is 1.04 g/mL. The NaOH leaves the electrolysis cell with 25–32% and must be monitored with density (D) or sound velocity (S) measurements to maintain safe concentrations and not to damage the membranes. °C), and that no heat is lost to the surroundings. The density is then used to compute volume or weight as needed. The molality of the solution is 1. density of sodium hydroxide is equal to 2 130 kg/m³; at 25°C (77°F or 298.15K) at standard atmospheric pressure.In Imperial or US customary measurement system, the density is equal to 132.972 pound per cubic foot [lb/ft³], or 1.231 ounce per cubic inch [oz/inch³] . The temperature of the solutions before mixing is was #20.0^@ C#; the final temperature is #26.0^@ C#. *) NTP – Normal Temperature and Pressure – is defined as air at 20°C and 1 atm Specific gravity is the ratio between the density (mass per unit volume) of the actual gas and the density of air, specific gravity has no dimension. NaOH is very soluble in water, and also in ethanol. Chemistry. The Questions and Answers of The density of 2M aqueous solution of NaOH is 1.28g/cm3 .

Calculate the mass of 8.00% w/w NaOH solution that contains 32.0 g of NaOH. Be aware of the concentration units in the figures: wt%: Mass of solute/total mass of solution*100% mol/kg: Molality = moles of solute/kg of water mol/liter: Molarity = moles of solute/liter of solution Values are tabulated below the figures. Many solutions used in separatory funnels are fairly dilute, so the density of the solution is approximately the same as the density of the solvent. It is commonly referred to as caustic soda due to its corrosive action on many substances it decomposes proteins at room temperatures and may cause chemical burn to human bodies. deg.
