Calculation path
Compare ideal effusion rates of two gases from their molar masses. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
Calculation path
r1/r2=sqrt(M2/M1)
What you receive
What you receive
- Rate ratio r1/r2 from the stated equation
- A symbolic formula plus substituted working with your values
- Visible assumptions, field guidance, and an authoritative learning reference
Use boundary
Choose the maximum decimal places shown. This does not increase source accuracy.
Both gases are compared at the same temperature through equivalent small openings in the molecular-flow limit.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
