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

Question:

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
