Q
Q: If 10 grams of NaCl is dissolved in 500 mL of water, what is the mass/volume percent concentration?
Solution:
Mass/volume percent = (mass of solute / volume of solution) x 100 = (10 g / 500 mL) x 100 = 2%.
Steps: 7
Show Steps
Step 1: Identify the mass of the solute (NaCl) which is 10 grams.
Step 2: Identify the volume of the solution (water) which is 500 mL.
Step 3: Use the formula for mass/volume percent concentration: (mass of solute / volume of solution) x 100.
Step 4: Plug in the values: (10 g / 500 mL) x 100.
Step 5: Calculate the division: 10 g / 500 mL = 0.02.
Step 6: Multiply by 100 to get the percentage: 0.02 x 100 = 2%.
Step 7: The mass/volume percent concentration is 2%.
