Calculate the molarity of each aqueous solution:
(a) 32.3 g of table sugar (C₁₂H₂₂O₁₁) in 100. mL of solution

Answer :

The molarity of table sugar in given solution is 0.94 M.

Molarity refers to number of moles of solute in solution whose volume is taken in liters. In this case, solute is table sugar. The formula to calculate molarity is -

Molarity = mass/(molar mass*volume)

Firstly converting volume from milliliters to liters. As we know, 1000 milliliters = 1 liters.

Volume of solution = [tex]\frac{1*100}{1000}[/tex]

Volume of solution = 0.1 l

Also, the molar mass of table sugar (C₁₂H₂₂O₁₁) is 342.3 g/mol.

Molarity = [tex]\frac{32.3}{342.3*0.1}[/tex]

Performing multiplication and division to find the molarity of table sugar in given volume

Molarity = 0.94 M

Hence, the molarity of table sugar in given solution is 0.94 M.
