Concentration of a solute can also be represented as a percentage by dividing the mg/L concentration, which also means ppm or "parts per million," by 10,000 to get parts per 100, or percentage. The ppm or mg/L notation is used more often because it is easier to comprehend....
Subtract the final mass of each bag from the initial mass of each bag. Multiply times 100 and divide the total by initial mass. This is the percentage change in mass. Note that in bag 4, there is no change in mass. Osmosis did not take place.

How To Find Percent Change In Mass

To calculate molarity, you may have to use conversion factors to move between units. For example, if you’re given the mass of a solute in grams, use the molar mass (usually rounded to two decimal places) of that solute to convert the given mass into moles.

  • The formula below for calculating body fat percentage was taken from research carried out in 1991 by Deurenberg which compared body mass index bmi and body composition. The relationship between body fat percentage and BMI was analysed taking the age and sex of participants into account and the formula below devised. The research showed that the estimates of body fat percentage according to …
