The 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"
The number of atoms in 6.4 grams of copper is 6.07X10^22. Copper has a melting point of 1084.62 degrees Celsius which is equal to 1984.32 degrees Fahrenheit.
10.5 * 10^-21
17.48 atoms
add 1.78 x 104 and 7.88 x 103 together and divide by 1.76 x 104 69.315%
by crystallisation, we can get pure copper sulphate crystals
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.

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.

in order to calculate the mean of the sample's mean and also to calculate the standard deviation of the sample's
if you have a water sample that contains either nitrate chloride.
Basic copper carbonate is prepared by combining aqueous.
The copper's density is 8.9 g/cm3
by crystallisation, we can get pure copper sulphate crystals
An atom. In a sample of copper, for instance, the smallest unit of copper that is still considered copper is a single atom of copper.
