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.

What does 70\% HNO3 mean?

70\% (w/w) Nitric acid means that 100 g of Nitric acid contains 70 g of HNO3. The density of 70\% (w/w)Nitric acid is 1.413 g/ml at 25°C which means that the weight of the 1 ml of Nitric acid is 1.413 gram at 25°C. For example, 1 mole of HNO3 is equal to 63.01 grams of HNO3 (molecular weight = 63.01).

How many grams is HNO3?

1 mole is equal to 1 moles HNO3, or 63.01284 grams.
