NEET Chemistry Concentration Terms MCQ Question
Type: MCQ-numerical-Easy-Class 12
What is the mass by volume percentage concentration of a solution if 5 grams of solute is dissolved to make a total solution volume of 100 mL?
A
5% (w/V)
B
10% (w/V)
C
0.5% (w/V)
D
50% (w/V)
Correct Answer
Option A
Detailed Explanation
Mass by volume percentage (w/V) is calculated as the mass of solute in grams divided by the volume of solution in mL, multiplied by 100. Thus, (5 g / 100 mL) * 100 = 5% (w/V).
