What each letter means
| Quantity | Unit |
|---|---|
| Total volume | L |
| Part 1 | L |
| Part 2 | L |
| Part 3 | L |
Worked example
Find the total volume when Part 1 = 7.8 L, Part 2 = 2.1 L, Part 3 = 0.1 L.
Using Vtotal = Σ Vi: Total volume = 10 L.
Frequently asked questions
What is the formula for Amagat's law?
Vtotal = Σ Vi.
What do the letters stand for, and what units are used?
Total volume in L, Part 1 in L, Part 2 in L, Part 3 in L.
How do you calculate total volume?
Put the values into Vtotal = Σ Vi. For example, with Part 1 = 7.8 L, Part 2 = 2.1 L, Part 3 = 0.1 L, total volume = 10 L.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (total volume, part 1, part 2, part 3) and fill in the others: it rearranges the formula for you.
