Learn how to calculate mass concentration, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
In chemistry, mass ratio, often called "percent composition by mass," is the proportion of a particular molecule that consists of each that molecule's constituent elements. For example, water consists of 11.1 percent hydrogen (H) and 88.9 percent oxygen (O), meaning that a 1,000-gram sample...

How to Calculate Mass Percent Concentration of a Solution Mass percentcomposition (also called mass percent or percent composition) is the easiest way to express the concentration of a solution because no unit conversions are required. Simply use a scale to measure the mass of the solute and the...
Chlorine-37 has an atomic mass of 36.966 amu and a percent abundance of 24.23%. To calculate the average atomic mass of chlorine, use the information in a periodic table of the element (see Resources) to find the (weighted) average but changing the percents to decimals: ...
Percent difference formula is given here along with solved example questions. Know how to apply the formula for percentage difference at BYJU'S.
To find the percent yield the actual yield is divided by the theoretical yield the resulting answer is multiplied by 100. What is the formula for the theoretical yield? We calculate the theoretical yield by taking the given mass of the reactants and multiplying it by the molar mass of the...
When thinking about the impact force of a falling object, you can calculate the energy of the object at its point of impact if you know the height from which it was dropped. This type of energy is known as gravitational potential energy and it is equal to the object's mass multiplied by...
It is equally important that the extraction conditions do not cause changes in the sample chemistry. Throughout the extraction process, the sample solution should be agitated. Either a mass basis or the surface area of the component being extracted can be used to determine the amount of ...
For instance, calculate the mass percent concentration for the solution obtained by dissolving 10 g of sodium chloride (NaCl) and 6 g of sodium bicarbonate (NaHCO3) in 120 g of water. Add up the mass of all compounds in the solution, including the solvent, to calculate the total mass of...
