What is the molar concentration of sucrose?

The molar concentration of sucrose can be calculated by determining the number of moles of sucrose dissolved in a specific volume of solution.

To find this value, you can follow these steps:

1. Determine the mass of sucrose: First, measure the mass of sucrose you have in grams.
2. Calculate the number of moles: Use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of sucrose (C₁₂H₂₂O₁₁) is approximately 342.3 g/mol.
3. Measure the volume of the solution: Next, measure the volume of the solution in liters (L). Make sure the volume is accurate for precise concentration calculations.
4. Calculate the molar concentration: Finally, use the formula: molar concentration (M) = moles of solute / volume of solution (L).

For example, if you dissolve 34.23 grams of sucrose in 1 liter of water, you would find:

• Moles of sucrose = 34.23 g / 342.3 g/mol = 0.1 moles
• Molar concentration = 0.1 moles / 1 L = 0.1 M

Therefore, the molar concentration of sucrose in this solution would be 0.1 M (molar).
