公式
## How to Calculate Dilution ### Formula **M1 × V1 = M2 × V2** Solving for M2: **M2 = (M1 × V1) / V2** Total moles of solute remain constant during dilution.
计算示例
Dilute 50 mL of 2 M HCl to a final volume of 200 mL.
- 01M2 = (M1 × V1) / V2
- 02M2 = (2 × 50) / 200
- 03M2 = 100 / 200
- 04M2 = 0.5 M
常见问题
What is the dilution equation?
M1V1 = M2V2 relates initial and final concentrations and volumes, assuming no solute is added or removed.
Does the equation work for all concentration units?
Yes, as long as both concentrations use the same unit and both volumes use the same unit.
Can I find the initial volume needed?
Yes, rearrange to V1 = (M2 × V2) / M1 to find how much stock solution you need.
