Find the atomic mass number of W. THen multipy that by the mass of a neutron (proton is about the same).
Then divide that into .0176grams. You may have to change units, depending on the mass units for the W atom.
Then divide that into .0176grams. You may have to change units, depending on the mass units for the W atom.
There are 6.02 x 10^23 atoms of W in a mole of W.
Step 1: Calculate the molar mass of tungsten.
The molar mass of tungsten (W) is approximately 183.84 grams/mol.
Step 2: Calculate the number of moles of tungsten in the filament.
The mass of the filament is given as 0.0176 grams.
We can use the formula: n = mass / molar mass.
n = 0.0176 g / 183.84 g/mol.
Step 3: Calculate the number of tungsten atoms in the filament.
We know that 1 mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23 particles/mol.
Therefore, the number of tungsten atoms in the filament is:
Number of atoms = n x Avogadro's number.
Substituting the values:
Number of tungsten atoms = (0.0176 g / 183.84 g/mol) x (6.022 x 10^23 atoms/mol).
Now, we can calculate this value to find the number of tungsten atoms in the filament.
