The easiest way is with a calculator. The formula is (Part / Whole) * 100. For example, to find what percentage 10 is of 50, you calculate (10 / 50) * 100 = 20%.
To calculate your CGPA, you typically multiply the grade points you earned in each subject by the subject’s credit hours, sum those results, and then divide by the total number of credit hours. Our tool helps convert the final CGPA to a percentage.
To convert a percentage back to CGPA, you would divide the percentage by 9.5. So, 75% is approximately a 7.9 CGPA (75 / 9.5 = 7.89).
The formula for percent by mass is (Mass of Solute / Mass of Solution) * 100. The Mass of the Solution is the mass of the solute plus the mass of the solvent. Our calculator above does this for you automatically.
A solution that is ‘20% by mass’ means that for every 100 grams of the total solution, 20 grams of it is the solute (the substance being dissolved).
Percent by mass is a way of expressing the concentration of a solution. It tells you what percentage of the solution’s total mass is made up of the solute.
