Sagot :
If forty five percent by mass of a 350 g mixture is composed of compound a, then 157.5 g of the mixture is compound a.
Percentage by mass, mass %, is a measure of concentration that indicates the mass of solute per mass of solution. In other words, the mass percent of a component in the solution is defined as the ratio of the mass of the component to the mass of the solution, expressed as a percentage.
mass % = (mass of solute / mass of solution) x 100
Substitute the given information into the equation.
mass % = 45
mass of solution/mixture = 350 g
Solve for the mass of compound a.
mass % = (mass of compound a / mass of mixture) x 100
45 = (mass of compound a / 350 g) x 100
mass of compound a = 157.5 g
