Moles of Unknown vs Moles of Known Substance
公式
## How to Use Mole Ratios ### Formula **moles_unknown = moles_known × (coeff_unknown / coeff_known)** The mole ratio comes directly from the balanced equation coefficients.
计算示例
3 mol of A with 2A -> 3B. How many moles of B?
- 01Mole ratio = 3/2
- 02Moles B = 3 × (3/2) = 4.5 mol
常见问题
What is a mole ratio?
The ratio of coefficients from a balanced equation, showing how many moles of one substance react with or produce another.
Where do coefficients come from?
From the balanced chemical equation. They are the numbers placed before each formula.
Can I use this for any pair of substances?
Yes, for any two substances in the same balanced equation, use their respective coefficients.
