The catch is that the audio CD is uncompressed. While you might have been able to put seven or eight hours of MP3s onto a single data CD before, youâre out of luck with an audio CD. These contain only about 70 minutes or so. It may take several audio CDs to hold what you might currently have on a single data CD.
Example 1: mass percent = (mass of chemical/total mass of compound) x 100 = (5 g/105 g) x 100. Example 2: We want to rearrange the mass percent equation to solve for the unknown mass of the chemical: mass of the chemical = (mass percent*total mass of the compound)/100 = (15*175)/100. 5. Calculate the mass percent.
Weight Loss Percentage Formula. The formula to calculate your weight loss percentage is: lbs lost divided by starting weight. Then, multiply the result by 100. Example: (5lbs / 150lbs) * 100 = -3.33%. So, if your starting weight is 150lbs and you lost 5lbs, youâve lost 3.33% of your body weight. Note: Please keep in mind, this calculates total weight loss including muscle. A better indicator of how you're doing would be to calculate how much body fat you're losing.
