## What is theoretical yield how it is calculated?

The theoretical yield is **the maximum possible mass of a product that can be made in a chemical reaction**. It can be calculated from: the balanced chemical equation. the mass and relative formula mass of the limiting reactant , and. the relative formula mass of the product.

## Is theoretical yield in grams or moles?

Theoretical yield is commonly expressed in **terms of grams or moles**. In contrast to theoretical yield, the actual yield is the amount of product actually produced by a reaction.

## How do you find theoretical yield in stoichiometry?

**The calculated or expected amount of product** is called the theoretical yield. The amount of product actually produced is called the actual yield. When you divide actual yield by theoretical yield you get a decimal percentage known as the percent yield of a reaction.

## How do you find theoretical value?

Alternate Wording. Accepted value is sometimes called the “true” value or “theoretical” value, so you might see the formula written in slightly different ways: **PE = (|true value – experimental value| true value) x 100%.**

## How do you find the theoretical yield of two reactants?

**Use the strategy:**

- Use molar mass of reactant to convert grams of reactant to moles of reactant.
- Use the mole ratio between reactant and product to convert moles reactant to moles product.
- Use the molar mass of the product to convert moles product to grams of product.

## How do you find the moles of a compound?

Determining Number of Moles of a Compound With Known Mass

To find the number of moles in a sample, **simply weigh it and divide the weight by the molecular weight**. The quotient is equal to the number of moles.

## How do you find the mole of an element in a compound?

**Divide the mass of the compound in grams by the molar mass you** just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or 1.39 moles.

## How do you find theoretical yield in mmol?

To determine “expected yield” of product, **multiply the reaction equivalents for the limiting reagent by the stoichiometric factor of the product**. This is the expected number of millimoles of product. Multiply this result by the MW of the product to determine the expected mass of the product.
