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.
LBM = BW â BF. Lean Body Mass equals Body Weight minus Body Fat. LBM + BF = BW. Lean Body Mass plus Body Fat equals Body Weight. The percentage of total body mass that is lean is usually not quoted â it would typically be 60â90%. Instead, the body fat percentage, which is the complement, is computed, and is typically 10â40%. The Lean body mass (LBM) has been described as an index superior to total body weight for prescribing proper levels of medications and for assessing metabolic disorders, as body fat is less relevant for metabolism.
