A scientist studied the effect of mixing two chemicals, Chemical A and Chemical B, by gradually adding more of each chemical to a mixture of the two. At the beginning of the study, the mass of Chemical A in the mixture was equal to the mass of Chemical B. From the beginning to the end of the study, the mass of Chemical A increased by 2,200% and the mass of Chemical B increased by 330%. At the end of the study, the mass of Chemical A was approximately how many times the mass of Chemical B?
