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.
20.3580 %. To calculate molar mass of a chemical compound enter it's formula and click 'Calculate!'. In chemical formula you may use: Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6] , CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.efinitions of molecular mass, molecular weight, molar mass and molar weight. 1  Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). 2  Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
