Why this conversion matters in chemistry
Fuel-ethanol blending math is one of the everyday contexts. A 10% v/v E10 gasoline blend is 100 mL/L on the laboratory ethanol-aqueous reference standard prepared for a GC-headspace blood-alcohol calibration. 10 mL/L per % v/v follows from the % v/v definition (mL per 100 mL) combined with the per-liter scale. In practice, this is the unit handoff between % v/v label specifications and mL/L bench-prep documentation.
Formula
mL/L = % v/v × 10
Worked Examples
1% v/v = 10 mL/L
The conversion anchor — 1 mL solute per 100 mL solution.
70% v/v = 700 mL/L
70% ethanol — the standard disinfectant strength.
0.1% v/v = 1 mL/L
About a trace liquid additive concentration.
95% v/v = 950 mL/L
Reagent-grade ethanol — the typical undenatured laboratory stock.
Frequently Asked Questions
How do I convert % v/v to mL/L?
Multiply by 10. So 70% v/v becomes 700 mL/L. The relationship is exact through the % v/v definition.
How do I prepare a % v/v solution?
Measure the required mL of solute, then add solvent to reach the final volume — not the other way around. For 5% v/v: 50 mL solute, then solvent to 1 L total. Mixing solute and solvent volumes additively can give the wrong final concentration because of partial molar volumes.
Is % v/v affected by temperature?
Yes — liquid volumes change with temperature, so % v/v shifts slightly. Always specify the temperature (usually 20 °C or 25 °C) when reporting precise % v/v values, especially for organic solvents with high thermal expansion.
