A chemistry student is provided with a mixture of two chemicals, A and B, but the quantity of each chemical is unknown. The student uses mass balance calculations to determine the mass of each component in the mixture. Chemical A has a molecular weight of 100 g/mol, while chemical B has a molecular weight of 120 g/mol. If the mixture contains 10% more of chemical A by mass than chemical B, what is the mass of each component in the mixture?
