WebSolution. The spinal fluid sample contains roughly 4 mg of glucose in 5000 mg of fluid, so the mass fraction of glucose should be a bit less than one part in 1000, or about 0.1%. Substituting the given masses into the equation defining mass percentage yields: % glucose = 3.75 mg glucose × 1 g 1000 mg 5.0 g spinal fluid = 0.075 %. WebIn chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. Expressed as a formula, the mass fraction is: =. Because the individual masses of the ingredients of a mixture sum to , their mass fractions sum to unity: = = Mass fraction can also be …
