Determine the molarity of a solution of concentrated nitric acid. Concentrated nitric acid is 70% by mass HNO3. The density of concentrated nitric acid is 1.42 g/ml
Although I understand Chemistry and have been doing well in the class, I just do not understand this problem. Thank you for any help!
Could anyone help me with this question? Thanks! Suppose you have a solution that contains 100 μg/mL of a substance in 500 μL. You wish to dilute this so that you have 50 μg/mL in 1...
Sulphuric acid is sold in standard stock solutions of concentration 14.5 M. A teacher needs to prepare 175 ml of 2.3 M solution of sulphuric acid.
