Moles of Unknown vs Moles of Known Substance
How to Use Mole Ratios
Formula
moles_unknown = moles_known × (coeff_unknown / coeff_known)
The mole ratio comes directly from the balanced equation coefficients.
Example Calculation
3 mol of A with 2A -> 3B. How many moles of B?
- 01Mole ratio = 3/2
- 02Moles B = 3 × (3/2) = 4.5 mol
