STANDARD Chemistry Molarity MCQ Question
What will be the molarity of the solution in which 0.365 g of HCl gas is dissolved in 100 mL of solution?
2M
0.2M
1M
0.1M
Correct Answer
Detailed Explanation
The number of moles of HCl is calculated as 0.365/36.5 = 0.01 moles. The volume of the solution in liters is 0.1 L. Molarity = n/V = 0.01/0.1 = 0.1M.
