Solution

Molarity (M) is a measure of the concentration of a solute in a solution, or of any chemical species in terms of amount of substance in a given volume. It is defined as the number of moles of solute per liter of solution.

Given: Mass of table sugar (C12H22O11) = 6.23 g Molar mass of table sugar = 342.30 g/mol Volume of tea = 250 mL = 0.250 L (since 1 L = 1000 mL)

Step 1: Calculate the number of moles of table sugar:

Number of moles = mass of substance (in grams) / molar mass (in g/mol)

Number of moles = 6.23 g / 342.30 g/mol = 0.0182 moles

Step 2: Calculate the molarity of table sugar:

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

Molarity (M) = 0.0182 moles / 0.250 L = 0.0728 M

So, the molarity of table sugar in a 250 mL cup of tea if 6.23 g of sugar was added is 0.0728 M.
