What is the concentration of sugar (C12H | Class 11 Chemistry Chapter Some Basic Concepts of Chemistry, Some Basic Concepts of Chemistry NCERT Solutions

Welcome to the NCERT Solutions for Class 11 Chemistry - Chapter Some Basic Concepts of Chemistry. This page offers a step-by-step solution to the specific question from Exercise 1, Question 11: . With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.

Question 11:

What is the concentration of sugar (C₁₂H₂₂O₁₁) in mol L^–1 if its 20 g are dissolved in enough water to make a final volume up to 2 L?

Answer:

Mass of sugar= 20g

Molecular mass of sugar=12x12 +1x22 +16x11=342 g

Mass of water= 2 liter

Molarity (M) = number of moles of solute/volume of solution in liters

= 20/(342x2) =0.02924 mol/liter

Therefore Molar concentration of sugar = 0.03 mol L^–1
