How many atoms has one hair got?
Suppose:formula of 'hair' is (averaged by) C10H18O5N2S and so this is with 36 atoms in one 'molecule'Its formula mass is (averaged by) [10*12.0+18*1.0+5*16.0+2*14.0+1*32.0] = 260 g/moland the mass of one hair is (averaged by) 1.0 mgThe answer can now be calculated, (controlled by 'unit analysis')[1.0*10-3(g) / 260(g/mol)] * 6.022*10+23(molecules/mol) * 36 (atom/molecule) =8*10+19 atoms (+/- 10%) per hair of 1 mg.
How can you calculate no of moles from no of atoms?
To calculate the number of moles from the number of atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Divide the number of atoms by Avogadro's number to find the number of moles.
How many times larger is the number of hydrogen atoms than oxygen atoms in water?
In a water molecule (H₂O), there are two hydrogen atoms for every one oxygen atom. This means that the number of hydrogen atoms is twice the number of oxygen atoms in water. Therefore, the number of hydrogen atoms is 2 times larger than the number of oxygen atoms.
What is the number of atoms of tin in 3 moles of tin?
The number of atoms is 18,066.10e23.
How many atoms are in heptane?
Heptane has a chemical formula of C7H16. To calculate the number of atoms in heptane, add the number of carbon atoms (7) to the number of hydrogen atoms (16), resulting in a total of 23 atoms in heptane.
How do you calculate atoms?
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms

What measurement in science is as exact as possible?
In theory, a measurement that is repeated an infinite number of times, or a very large number of times and then averaged.
What are Atoms with the same number of protons are?
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
How do you convert chlorine atoms to moles of chlorine atoms?
To convert the number of chloride atoms to mols of chlorine atoms, simply multiply by Avogadro's number. This number is 6.022E23. Note that chlorine typically exists as a diatomic molecule, consisting of two chlorine atoms.
How many times larger is the number of hydrogen atoms than oxygen atoms in water?
In a water molecule (H₂O), there are two hydrogen atoms for every one oxygen atom. This means that the number of hydrogen atoms is twice the number of oxygen atoms in water. Therefore, the number of hydrogen atoms is 2 times larger than the number of oxygen atoms.
Every balanced chemical equation each side has the same number of?

Does the number of iron atoms in the reactants equal the number of iron atoms in the products?
no
What is the number of atoms of tin in 3 moles of tin?
The number of atoms is 18,066.10e23.
How many atoms are in heptane?
Heptane has a chemical formula of C7H16. To calculate the number of atoms in heptane, add the number of carbon atoms (7) to the number of hydrogen atoms (16), resulting in a total of 23 atoms in heptane.
How does a number of H Atoms in a carbohydrate compared to the number of oxygen atoms?
It depends on how many hydrogens are there and how many oxygen atoms there are.
