### How to calculate E pt?

**P** = 1500W. **you** = 23 min (compulsory conversion, i.e. in s => **E** in J, or in h => **E** in Wh)…The energy formula.

Literal formula | E = P xt |
---|---|

Units adopted by EDF/ERDF | Wh = W xh |

Details | E : energy in joule (J) or in watt-hour (Wh) P : power in watts (W) you : time in seconds (s) or in hours (h) |

### How to calculate the energy E?

**Energy** Electric **E**=P*t | Superprof.

### How to calculate the yield of a product?

Definition of yield It is denoted ρ and equals: The mass of product obtained is the mass synthesized. It is determined by weighing the product obtained.

### How to calculate the yield of a reaction?

Yield calculation. Consider the reaction allowing the synthesis of a following product C. A + 2B C. The first step is to calculate the number of moles of reactants A and B in order to determine the limiting reactant.

### What are yield losses?

Yield losses can have various origins: parasitic reactions, losses during the various stages of the synthesis (filtration, drying, recrystallization, etc.) The mass of product obtained is the mass synthesized. It is determined by weighing the product obtained.
