How many grams of concentrated nitric acid solution used to prepare 250 ml of 2 M nitric acid concentrated nitric acid is 70\% pure?
We now calculate the weight of \[HNO_3\] in 250 mL of solution. is present in 100g of solution. Hence, Option (D) 45.0g of conc. \[HNO_3\] is the correct answer.
How do you make a 5\% nitric acid solution?
The volume of 7.14 g of concentrated HNO3 can be obtained from the density V = 7.14 g / 1.42 = 5.03 mL. If you then measure 5.03 mL of the concentrated HNO3 and dilute to 100 mL with water, you would have the required 5\% solution.
How do you make a 1m solution of nitric acid?
Add 64.1mL, or 90.4g, of SEASTAR™’s Nitric Acid to water up to 1L to make a 1 Molar Solution of Nitric Acid.
How is dilute nitric acid prepared?
3.2 Pour about 75.0 ml of distilled water into a 250 ml capacity beaker. 3.3 Transfer slowly, through sidewalls of the beaker, 10.6 ml of Nitric Acid LR into above said beaker, while gentle mixing, by using a glass rod. 3.4 Transfer prepared solution into a 100 ml volumetric flask by using a glass funnel.
How do you calculate nitric acid?
Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70\% HNO3 to be 1413 grams. Knowing that the solution is 70 wt \% would then allow the number of grams of HNO3 to be calculated: (0.700)(1413g) = 989.1 grams HNO3 per liter.
How do you calculate the percentage of nitric acid?
Find the total mass of the nitric acid HNO3 Then divide the mass of each atom by the total mass to find the percentage.
How do you make a 1 molar solution of nitric acid?
1L contains 15.6 moles, therefore 1 mole is contained within = 1L / 15.6 moles. Add 64.1mL, or 90.4g, of SEASTAR™’s Nitric Acid to water up to 1L to make a 1 Molar Solution of Nitric Acid.
How do you make 6 molar nitric acid?
For example, to make 500 mL of 6M HCl, use 250 mL of concentrated acid and slowly dilute to 500 mL with water….Recipes for Acid Solutions.
| Name / Formula / F.W. | Concentration | Amount/Liter |
|---|---|---|
| Nitric Acid | 6 M | 380 mL |
| HNO3 | 3 M | 190 |
| F.W. 63.01 | 1 M | 63 |
| 70.0\%, 15.8 M | 0.5 M | 32 |
How many grams of concentrated nitric acid should be used to prepare?
Thus 45.0 g conc. H N O3 of concentrated nitric acid solution should be used to prepare 250 mL of 2.0 M H N O3
How do you make a 2\% nitric acid solution?
For a 2\% solution the final weight of solution will be 13.4/.02=670 grams. Therefore add 670–13.4=656.6 g of H2O, giving 670 g of 2\% HNO3. How can I prepare 100\% nitric acid? You cannot convert concentrated nitric acid into anhydrous nitric acid by distillation, because the standard concentration is an azeotrope.
What is the percentage of nitric acid in 100 ml of water?
so, 0.7246 ml of 69\% Nitric acid added with 99.275 ml of water forms 100 ml of 0.5\% Nitric acid.
How much HNO3 = 32\% nitric acid?
So : 470.6 ml of 68\% HNO3 diluted to* 1000 ml ( when cooled down back to lab temp ), will give you 1 liter of 32\% nitric acid Mind you : not 470 ml plus 1000 ml of water, but 470.6 + water up to 1000 ml !
