How many moles of HNO3 are needed to prepare 5.0 liters of 2.0m soultion of HNO3?
Concentration of NaOH = 0.025 M = 0.025 Moles per Litre of SolutionVolume of Solution required = 5.00LWe can say therefore that:Number of Moles of NaOH needed to prepare the solution= Concentration of NaOH * Volume of Solution requiredTherefore:Number of Moles of NaOH needed to prepare the solution= 0.025M * 5.00L= 0.125molesFrom this we can say that 0.125 moles of NaOH are needed to prepare a 5.00 L solution with a concentration of 0.025M of NaOH.

How do you prepare M Cal solution?
To prepare 1 M CaI aqueous solution, dissolve 29.4 g in a total volume of 100 mls, or 294 g in a total volume of 1 liter.
How do you prepare PVA aqueous solution?
Denpending of the concentrations, you can use only mechanical agitation and elevate temperature for 5 to 15 minutes.
How do you prepare solution in ppm?
You prepare a primary solution then dilute portion of your solution down to the required concentration. For example, you want a 10 ppm salt solution (10 mg/L), you dilute 1 g of salt in 1 L of water you get 1000 ppm salt solution. You take 10 ml of your salt solution (0.01 g salt in 10 g) and add in additional 980 ml of water then you get a 10 ppm weight solution.
