JEE Main 2025 Chemistry question
Concentrated nitric acid is labelled as 75% by mass. The volume in mL of the solution which contains 30 g of nitric acid is . Given : Density of nitric acid solution is 1.25 g/mL
Answer: (3)
Solution
75g HNO3 in 100/1.25 mL solution; 30g HNO3 present in (100×30)/(1.25×75) = 32 mL
