The diameter of the tungsten wire in a lightbulb filament is very small, less than two thousandths of an inch, or about 1/20 mm. the mass of the filament is so very small - 0.0176 grams - that it would take 1600 filaments to weigh an ounce! how many tungsten atoms are in a typical lightbulb filament?

A typical lightbulb filament, whose mass is 0.0176 g, contains 5.76 × 10¹⁹ atoms of tungsten.

The mass of a typical lightbulb filament of tungsten is 0.0176 grams. We can convert 0.0176 g to moles using the molar mass of tungsten (183.84 g/mol).

To convert 9.57 × 10⁻⁵ mol to atoms, we will use Avogadro's number: there are 6.02 × 10²³ atoms in 1 mole of atoms.

The number of tungsten Atoms in a typical light bulb filament is

5.76 ×  atoms of W

Explanation:

Write the given values of the problem

The diameter the tungsten wire in a light bulb filament Tungsten element W : molar mass = 183.84 g / mol

0.0176 g W ×   = 0.000096 mol W

0.000096 mol W ×  }{1 mol W}" alt="10^{23 atoms}" />}{1 mol W}" />

= 5.76 × atoms of W
