Questions & Step-by-Step Solutions
If 50 mL of 0.1 M H2SO4 is diluted to 250 mL, what is the new concentration?
Step 1: Identify the initial concentration (C1) and volume (V1) of the solution. Here, C1 is 0.1 M and V1 is 50 mL.
Step 2: Identify the final volume (V2) after dilution. Here, V2 is 250 mL.
Step 3: Use the dilution formula C1V1 = C2V2, where C2 is the new concentration we want to find.
Step 4: Plug in the known values into the formula: (0.1 M)(50 mL) = C2(250 mL).
Step 5: Calculate the left side: 0.1 M * 50 mL = 5 M*mL.
Step 6: Set up the equation: 5 M*mL = C2 * 250 mL.
Step 7: To find C2, divide both sides by 250 mL: C2 = 5 M*mL / 250 mL.
Step 8: Calculate C2: C2 = 0.02 M.
Dilution of Solutions – This concept involves understanding how to calculate the concentration of a solution after it has been diluted using the formula C1V1 = C2V2.
