∙ 12y agoThe mass of the sample of copper, as stated in the question, would be 63.5g. The mass of a single atom would be 63.5 AMU (Atomic Mass Units). In grams, the single atom has a mass of 1.054×10^-22 grams.
P.S. The "^" symbol means "to the power of"

If a sample of copper contains 1.76E 4 atoms of copper-63 and 7.88E 3 atoms of copper-65 what is the percentage of copper-63 atoms in the sample?
add 1.78 x 104 and 7.88 x 103 together and divide by 1.76 x 104 69.315%
Which methods is used to obtain pure copper sulphate from impure sample and how?

Which sample contains the greatest number of atoms a sample of Mn that contains 3.29E plus 24 atoms or a 5.18 mole sample of you?
Which sample contains the greatest number of atoms. A sample of Mn that contains 3.29E+24 atoms or a 5.18 mole sample of I?The sample of _____ contains the greatest number of atoms.Answer:In order to compare the two samples, it is necessary to express both quantities in the same units. Since the question was phrased in terms of atoms, it is convenient to convert moles of I to atoms of I.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.18 moles of I to atoms of I:atoms I= 5.18 mol I6.02 x 1023 atoms I = 3.12E+24 atoms I1 mol IMultiply by atoms per mole. Moles cancel out.The sample of Mn contains 3.29E+24 atoms.Since 3.12E+24 is smaller than 3.29E+24, the sample of Mn contains the greatest number of atoms.

How do you calculate the amount of CuS and Cu2S in an ore sample given a known sample amount and amount of impurity?
Copper metal can be prepared by roasting copper ore, which can contain cuprite (Cu2S) and Copper (II) sulfide. Cu2S + O2 -> 2Cu + So2 CuS + O2 -> Cu + SO2 Suppose an ore sample contains 11.0% impurity in addition to a mixture of CuS and Cu2S. Heating 100.0 g of the mixture produces 75.4 g of copper metal with a purity of 89.5%. What is the weight percent of CuS in the ore? The weight percent of Cu2S? Clicked enter too fast, sorry.
