How the Scientist Mixes 150 mL of 0.4 M Glucose with 350 mL of 0.2 M Glucose—Actually Works

To find the final molarity, the total moles of glucose must be divided by the total volume of the mixed solution. Starting with 150 mL (0.15 L) of 0.4 M glucose provides 0.06 moles:
0.15 L × 0.4 mol/L = 0.06 mol.

Adding 350 mL (0.35 L) of 0.2 M glucose contributes 0.07 moles:
0.35 L × 0.2 mol/L = 0.07 mol.

Together, the total moles equal 0.13 mol. The final volume is 150 + 350 = 500 mL or 0.5 L. Dividing moles by volume gives:
0.13 mol ÷ 0.5 L = 0.26 M.

This result reflects how dilution and concentration work together—critical for maintaining safety and consistency in lab and clinical workflows.

Common Questions Explained

Q: Does mixing glucose solutions dilute or concentrate the final drink?
A: Mixing reduces overall concentration because volume increases while total moles stay the same—dilution typical in scientific mixing.

Q: Why can’t I just add the concentrations directly?
A: Concentration depends on volume; mixing requires volume summation and mole tracking to avoid misleading averages.

Q: How accurate does this calculation need to be in real labs?
A: For research and education, precision above ±0.01 M ensures reliable outcomes, supporting consistent experimental results.

Frequently Misunderstood Facts

A common myth is that mixing equal volumes doubles concentration—that’s only true if moles are unchanged, not mixed. Another error is ignoring unit conversion
