Question

In the process of solving, it was changed to Kgmolecule-1 after adding Avogadro number. However, in the process of obtaining the value of frequency, the unit of the value of the micro was changed to kg. What is the reason?

Convert from g mol-¹ to kg mol-¹....
6.856 g mol-¹
1000
Note that;
...then divide by Avogadro's number to obtain a value in kg molecule ¹;
6.856 × 10-³ kg mol-1
6.022 x 1023 molecules mol-1
6.856 × 10-3
1
2 x 3.141
then substitute values in for each of the variables;
X
V
1 = 2/1/2 √ / / 20
2π
kg mol-1
= 1.14 x 10-6 kg molecule-¹
1903 N m-¹
1.14 x 10-726 kg
