How to Calculate and Solve for Percentage Yield, Actual Yield and Theoretical Yield in Chemistry | The Calculator Encyclopedia

The image above represents percentage yield.

To compute the percentage yield, two essential parameters are needed and these parameters are actual yield and theoretical yield.

The formula for calculating percentage yield:

%Yield = (Actual YieldTheoretical Yield) x 100

Let’s solve an example;
Find the percentage yield when the actual yield is 12 with a theoretical yield of 26.

This implies that;
Actual yield = 12
Theoretical yield = 26

%Yield = (Actual YieldTheoretical Yield) x 100
%Yield = (1226) x 100
%Yield = 0.46 x 100
%Yield = 46.15

Therefore, the percentage yield is 46.15.

Calculating the Actual Yield when the Percentage Yield and the Theoretical Yield is Given.

Actual yield = %yield x theoretical yield / 100

Let’s solve an example;
Find the actual yield when the %yield is 52 with a theoretical yield of 10.

This implies that;
%yield = 52
Theoretical yield = 10

Actual yield = %yield x theoretical yield / 100
Actual yield = 52 x 10 / 100
Actual yield = 520 / 100
Actual yield = 5.2

Therefore, the actual yield is 5.2.

Nickzom Calculator Solves Molar Concentration in Chemistry

According to Wikipedia,

Molar concentration (also called molarityamount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution. In chemistry, the most commonly used unit for molarity is the number of moles per litre, having the unit symbol mol/L. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M.

Nickzom Calculator Solves Calculations on Gas Laws

In Physics and Chemistry, there are four prominent gas laws that govern calculations related to gases. These laws have major parameters such as:

  • Pressure
  • Temperature
  • Volume

The four gas laws are:

  • Boyle’s Law
  • Charles’ Law
  • Pressure or Gay Lussac’s Law
  • The General Gas Equation

According to Boyle’s law, pressure is indirectly proportional to volume.

According to Charles’ law, volume is directly proportional to temperature.

According to Pressure or Gay Lussac’s law, pressure is directly proportional to temperature.

According to the General Gas Equation or law, the product of pressure and volume is directly proportional to temperature.
