How do you dilute 70\% HNO3?
After the solid is completely dissolved, dilute the solution to a final volume with deionized (distilled) water. we will need to dilute 6.37 mL of 70 \% HNO3 to a final volume with deionized (distilled) water. Transfer the prepared solution to a clean, dry storage bottle and label it.
How much HNO3 do you mix with water to make solution?
That is to say: Mix 16.23 mL of 69\% HNO3 with 483.78 mL of water to prepare 500 mL of an 0.5 N HNO3 solution. Save up to 80\% on your next printer ink cartridges!
What is the volume of 65\% HNO3 in dH2O?
However, HNO3 65\% is 65 g HNO3 in 100 ml dH2O and Mw of HNO3 is 63.01 g/mol. Therefore, 2.5 M (2.5 N) is prepared with 157.525 g in 1000 ml. If you pick 242.346 ml of 65\% HNO3 (EQUAL TO 157.525 g HNO3) and reach its volume to 1000 ml with dH2O, At that time, you have 2.5 M (N) of HNO3. If you have any questions, please dont hesitate to contact me.
What is the concentration of undiluted HNO3 in aqueous solution?
Indeed, the concentration of the undiluted HNO 3 aq. would be 65 wt\%, i.e. (g HNO 3 / g solution)·100\%. The density of that concentrated acid as 1.391 g/cm 3 (20 ºC) (cf. e.g. Perry’s Chemical Engineers’ Handbook). The density is usually also available from the commercial label. The molecular mass of HNO 3 is 63.012 g·mol −1.
What is the specific gravity of concentrated HNO3?
The conc. acid is 70\% (w/v) HNO3. As density or specific gravity of concentrated HNO3 is not given, we can not proceed further. The percentage, purity of commercial HNO3 is 68\% (w/w) and the specific gravity of the solution is 1.51 g/ml.
How do you calculate the normality of 69\% HNO3?
First, calculate the normality of 69\% HNO3. Each mL of the acid has a mass of 1.41 gms, 69\% of which is HNO3. That is 0.9729 gms HNO3/ mL. The Molecular weight of HNO3 is 63.
