A brass alloy contains 82.5% copper, Cu, by mass with the remainder of the alloy being zinc, Zn. Determine the number of moles of zinc in 41.2 g of the brass alloy. moles of Zn = Determine the number of atoms of zinc in 41.2 g of the brass alloy. atoms of Zn =
A certain metal hydroxide, , contains 32.8 oxygen by mass. What is the identity of the metal ? Let X be the molar mass of M(OH)2 32/X = 0.328 X = 97.6 g/mol Molar mass of metal M = 97.6 - 32 - 2 = 63.56 g/mol According to the periodic table, copper has the molar mass of 64g/mol. So, M is copper. Why do you divide by 32 in the numerator instead of 32.8? if it is 32.8g of...
A 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. The reaction was stopped before all the nickel reacted, and 36.5 g of solid metal (nickel and silver) is present. Calculate the mass of solid silver metal present.

Chromel is an alloy composed of nickel, iron, and chromium. A 0.6445-g sample was dissolved and diluted to 250.0 mL. When a 50.00-mL aliquot of 0.05173 M EDTA was mixed with an equal volume of the diluted sample, all three ions were chelated, and a 5.23-mL back-titration with 0.06139 M copper(II) was required. The chromium in a second 50.0-mL aliquot was masked through the addition of hexamethylenetetramine; titration of the Fe and Ni required 38.95 mL of 0.05173 M EDTA....
