Calculate the mass, in grams, of a single tungsten atom (mw = 183.84 amu ).

The formula for number of moles is :

    -(1)

The atomic mass of tungsten =   (given)

Number of atoms of tungsten = 1

Since, 1 mol =

So, number of moles of tungsten =

Rearranging the formula (1) as:

Substituting the values:

Hence, the mass of a single tungsten atom (mw = 183.84 amu ) is .

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hope i !

it's c (engineer's do their work with mechanical stuff not on any living being)
