Question

calculate the mass of an atom of silver atomic mass 108

Answer 1

Mass is $\bold{17.93 \times 10^{-23}}$ grams.

SOLUTION:

The mass of any of the atoms asked to us can be calculated by a Y diagram concept of mole theory. We know that the value of Avogadro number is $6.022 \times 10^{23}$

So here it is given that the mass of silver atom is 108 g , which will be the given mass.

Thus, Mass of $6.022 \times 10^{23}$ atoms of silver is 108 g.

Now,  

Calculating the mass for 1 atom particularly  

Mass of one atom of silver is

$=\frac{108}{6.022 \times 10^{23}}$$=17.93 \times 10^{-23} grams.$

Answer 2

Answer:

1.7913 x 10 ^ -22g

Explanation:

1 mol Ag=107.87g

6.022 x10^23  a t o m s  A g = 107.87 g

1 atom Ag = 1.7913 x 10 ^ -22g
