Typically brass contains 67% (w/w) copper (Cu) and 33% (w/w) zinc (Zn). Find the number of moles of each component (Cu and Zn) contained in a 125 g sample of brass. (Cu = 63.55 g/mol, Zn = 65.38 g/mol)

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
