NEET Chemistry Van't Hoff Factor MCQ Question
Type: MCQ-fact-Hard-Class 12
What is the molarity of a solution containing 5 g of NaOH in 450 mL of solution?
A
0.125 M
B
0.250 M
C
0.500 M
D
0.375 M
Correct Answer
Option A
Detailed Explanation
To find the molarity, first calculate the moles of NaOH using its molar mass. The moles are 0.125 mol, and the volume in liters is 0.450 L, leading to a molarity of 0.125 M as calculated from the formula M = moles/volume.
