How to Calculate Mass Percentage
What is the formula to calculate mass percentage?
A. Mass Percentage = (Mass of solute / Total mass of solution) x 100
B. Mass Percentage = (Mass of solution / Mass of solute) x 100
C. Mass Percentage = (Mass of solvent / Total mass of solution) x 100
D. Mass Percentage = (Total mass of solution / Mass of solvent) x 100
Answer:
The correct formula to calculate mass percentage is option A. Mass Percentage = (Mass of solute / Total mass of solution) x 100.
Mass percentage is a way to express the concentration of a solute in a solution. It is calculated by dividing the mass of the solute by the total mass of the solution and then multiplying by 100 to get the percentage.
For example, if you have 20 grams of salt dissolved in 80 grams of water, the total mass of the solution would be 100 grams. To calculate the mass percentage of salt in the solution, you would use the formula: (20 / 100) x 100 = 20%. This means that the solution contains 20% salt by mass.
By knowing the mass percentage of a solute in a solution, you can determine the concentration and make informed decisions in various scientific fields such as chemistry, biology, and environmental science.
