a watch glass and filter paper weighing 41.060g was used to collect the CuSCN precipitate in this experiment. After drying, the precipitate, watch glass and filter paper weighed 42.525g. If the sample of alloy used for the analysis weighed 1.380g, what was the percent copper in the alloy

find the net weight of the CuSCN.
of that net weight, determine the mass of the Cu. PercentCu=atomicmassCu/(molemassCuSCN)
grams Cu=massCuSCN*percentCu.
percentCu in alloy used= massCuabove/massalloy * 100
