QNEET-2013-Ch-1473: NEET 2013 Chemistry - Class 11 NEET-2013-Ch-1473 Solution: How many grams of concentrated nitric acid solution should be…
How many grams of concentrated nitric acid solution should be used to prepare 250 mL of 2.0 M ? The concentrated acid is 70% . 70.0 g conc. 54.0 g conc. 45.0 g conc. 90.0 g conc.
Multiple Choice Options
- A 70.0 g conc. HNO 3
- B 54.0 g conc. HNO 3
- C 45.0 g conc. HNO 3
- D 90.0 g conc. HNO 3
Step-by-Step Verified Solution
2 = m 63 _ 0.25
_ m = 2 _ 63 _ 0.25 = 31.5 g
Now, if concentrated HNO 3 is 100% then it requires
31.5 g.
But the original solution of HNO 3 is 70%
concentrated.
Hence, the mass of HNO 3 required to
produce 2.0 M solution
= 100 75 _ 31.5
= 45 g of HNO 3
