The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
To find the number of atoms in the sample, we need to first calculate the number of moles of nickel present in the sample using its molar mass. The molar mass of nickel is 58.69 g/mol. Dividing the mass of the sample by the molar mass gives us 0.200 moles of nickel. Finally, multiplying this by Avogadro's number (6.022 x 10^23 atoms/mol) gives us approximately 1.20 x 10^23 atoms in the sample.
How many oxygen atoms are present in one molecule of nickel hydroxide?
In one molecule of nickel hydroxide, there are two oxygen atoms. This is because the chemical formula for nickel hydroxide is Ni(OH)2, meaning there are two hydroxide groups, each containing one oxygen atom.
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?
The answer is 6,31 moles Ag.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many Ag atoms are there in a 88.1 gram sample of Ag?
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.

How many atoms are present in a 15 mol sample of uranium?
Approx. 9.1024 atoms.
How many nickel atoms are present in 5.6 moles of nickel metal?
Avogadro's number times 5.6 (or about 33.6 times ten to the 23rd power.
Is a nickel a mixture or pure substance?
Nickel is a chemical element; therefore, any object that contains only nickel is a pure substance.
How many oxygen atoms are present in one molecule of nickel hydroxide?
In one molecule of nickel hydroxide, there are two oxygen atoms. This is because the chemical formula for nickel hydroxide is Ni(OH)2, meaning there are two hydroxide groups, each containing one oxygen atom.
How many C-13 atoms are present on average in a 13000-atom sample of carbon?
Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.
How many total atoms are in one molecule of nickel hydroxide Ni OH2?
Ni(OH)2 1 atom of nickel 2 atoms of oxygen 2 atoms of hydrogen -------------------------------+ total atoms = 5 atoms
If a sample is 10740 years old and has 400 atoms how many atoms are there after the organisms died?
After 10740 years, half of the sample would have decayed, so there would be 200 atoms left. If the original sample had 400 atoms, then there would be 200 atoms left in the sample after 10740 years.
How do you find out how many atoms are present in calcium?
To find out how many atoms are present in calcium, you would need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Simply divide the mass of the calcium sample by the atomic mass of calcium (40.08 g/mol) and then multiply by Avogadro's number to determine the number of atoms present.
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?
The answer is 6,31 moles Ag.
According to Dalton how do the atoms from one sample of the element carbon compare to the atoms of another sample of carbon?
They are identical.
