Yes. 16.00g of oxygen is its molar mass, which is the mass of one mole of oxygen. 4.003g is the molar mass of helium, which is also the mass of one mole of helium. One mole of anything is 6.022 x 1023. One mole of oxygen atoms is 6.022 x 1023 atoms of oxygen and one mole of helium atoms is 6.022 x 1023 atoms of helium.
neutrons, protons and electrons. _________ The above is incorrect; those are atomic particles. Subatomic particles are what those particles are made of. Quarks and leptons are subatomic particles.
A crystal lattice sample contains particles arranged in a regular geometric pattern. This can be seen in substances like salt or sugar where the particles are arranged in a repeating pattern to form a crystal structure.
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.
In each nitric acid molecule (HNO3), there is one oxygen atom. So, in a sample containing 50 HNO3 molecules, there would be 50 oxygen atoms.
One way to determine that a sample of a mystery gas is oxygen is to perform a combustion test. If the gas supports combustion, creating a flame when exposed to a flame, it is likely oxygen. Additionally, using a chemical reaction with hydrogen peroxide and a catalyst to produce oxygen gas can also confirm the presence of oxygen in the sample. Finally, utilizing a gas sensor or gas chromatography to analyze the composition of the gas would further confirm if it contains oxygen.

If the soil sample has 30 million particles of soil and 60 of those particles are sand, then the number of soil particles that are sand is 60. Sand particles represent 0.000002% of the total particles in the soil sample.
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.

The ratio of mass of copper to oxygen in the sample is 4:1. This is determined by dividing the mass of copper (64 g) by the mass of oxygen (16 g).
The pressure is 103,5 at.
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.
The gas that contains the most molecules in a 5.0 L sample would be the one with the highest molar mass. This is because the number of molecules in a gas sample is directly proportional to its molar mass.
