Solution

Sure, here are the steps to calculate the molarity of the sugar solution:

  1. First, we need to convert the mass of the sugar cube from grams to moles. The molar mass of sucrose (C12H22O11) is approximately 342.3 g/mol. So, 4 g of sugar is 4 g / 342.3 g/mol = 0.0117 moles.

  2. Next, we need to convert the volume of the water from milliliters to liters. 350 ml is equal to 0.35 liters.

  3. Finally, we calculate the molarity of the solution by dividing the number of moles of sugar by the volume of water in liters. So, the molarity is 0.0117 moles / 0.35 liters = 0.0334 M.

So, the molarity of the sugar solution is 0.0334 M.
