Questions & Step-by-Step Solutions
If 15 grams of sugar is dissolved in 250 mL of water, what is the molarity of the solution? (Molar mass of sugar = 180 g/mol)
Steps
Concepts
Step 1: Find the number of moles of sugar. Use the formula: Moles = Mass (g) / Molar mass (g/mol). Here, Mass = 15 grams and Molar mass = 180 g/mol.
Step 2: Calculate the moles of sugar: 15 g / 180 g/mol = 0.0833 moles.
Step 3: Convert the volume of water from mL to L. Since 1 L = 1000 mL, 250 mL = 0.25 L.
Step 4: Calculate the molarity of the solution using the formula: Molarity (M) = Moles of solute / Volume of solution (L).
Step 5: Substitute the values: Molarity = 0.0833 moles / 0.25 L.
Step 6: Calculate the molarity: 0.0833 moles / 0.25 L = 0.333 M.
Molarity
– Molarity is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution.
Moles Calculation
– Calculating moles involves dividing the mass of the solute by its molar mass.
Volume Conversion
– Understanding that 250 mL is equivalent to 0.25 L is crucial for calculating molarity.
