NEET Chemistry Concentration terms MCQ Question
Calculate molarity of 63% w/w HNO₃ solution if density is 1.4 g/mL.
14 M
12 M
10 M
8 M
Correct Answer
Detailed Explanation
Molarity is calculated using the formula: Molarity = (density × percentage × 10) / molar mass. For HNO₃, molar mass is 63 g/mol. Thus, M = (1.4 × 63 × 10) / 63 = 14 M.
