Which sample contains the greatest number of atoms a sample of Al that contains 8.18E plus 23 atoms or a 5.16 mole sample of S?
Which sample contains the greatest number of atoms. A sample of Al that contains 8.18E+23 atoms or a 5.16 mole sample of S?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 S to atoms of S.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.16 moles of S to atoms of S:atoms S=5.16 mol S6.02 x 1023 atoms S= 3.11E+24 atoms S1 mol SMultiply by atoms per mole. Moles cancel out.The sample of Al contains 8.18E+23 atoms.Since 3.11E+24 is larger than 8.18E+23, the sample of S contains the greatest number of atoms.
What does a core sample consist of?
A cylindrical section of a naturally occurring substance firm enough to hold a layered structure. Samples are obtained using a hollow steel tube called a core drill. The sample is obtained more or less intact from the strata being sectioned. From Wikipedia.com

How many metric tons of oxygen are combined in a sample of pitchblende that contains 1.8 tons of uranium?
To determine the amount of oxygen combined in the sample of pitchblende, we use the chemical formula of pitchblende, which is U3O8. The molar ratio of uranium to oxygen in U3O8 is 3:8. Given that there are 1.8 tons of uranium in the sample, we calculate the amount of oxygen by multiplying 1.8 tons of uranium by the ratio of oxygen to uranium (8/3). This yields approximately 4.8 tons of oxygen combined in the sample of pitchblende.
A sample is prepared by completely dissolving 10.0 grams of NaCl in 1.0 liter of H2o. which classification best describes this sample?
The sample described is a saturated solution because it contains the maximum amount of NaCl that can dissolve in 1.0 liter of water at that temperature.
What approximate mass would a sample of naturally occurring boron (B) that contains 1 and times 106 atoms of boron have?
The molar mass of boron is approximately 10.81 g/mol. To calculate the mass of 1 x 10^6 boron atoms, you divide 6.022 x 10^23 (Avogadro's number) by 1 x 10^6 to find the number of moles, which equals 0.001673 moles. Multiply this by the molar mass of boron to get approximately 0.0181 grams.
How might you identify whether a mineral sample might be lodestone?
One way to identify if a mineral sample might be lodestone is through its magnetic properties. Lodestone is a naturally occurring magnet, so it will attract materials like iron. You can test this by seeing if the sample is attracted to a magnet. Additionally, lodestone is typically a form of magnetite, so if the sample looks similar to magnetite in appearance, it could be lodestone.
What approximate mass would a sample of naturally occurring boron (B) that contains 1 x 106 atoms of boron have?
The molar mass of boron is approximately 10.81 g/mol. To find the mass of 1 x 10^6 atoms of boron, divide the number of atoms by Avogadro's number to get the number of moles, then multiply by the molar mass of boron. Therefore, the mass of 1 x 10^6 boron atoms would be approximately 1 x 10^-5 grams.
What is the density of palladium 106?
Palladium consists of several isotopes. The density of a naturally occurring sample, which is a mixture of isotopes is 12.02 g/cm3. I have no reference material for individual isotopes. There is a book called the CRC Handbook of Chemistry and Physics which may have this information.

What is an atomic mass of an element?
The atomic mass of an element is the weight of the constituent atomic paraticles in an atom of a given isotope. The atomic weight is the weighted average mass for atoms in a naturally occurring sample of the element.Almost all of an atom's mass is found in the nucleus, consisting of protons and neutrons.
