A laboratory has two calcium carbonate sources: a reagent-grade powder that is 98.0% CaCO3 by mass and an ore that is 60.0% CaCO3 by mass. What masses of each source are required to prepare 250.g of a mixture that is 85.0% CaCO3 by mass? Report the required mass of the 98.0% powder first, followed by the mass of the ore.
