Correct option is (1) 108
We know,
According to Avogadro's law, 1 mole of every substance weighs equal to the atomic mass and contains Avogadro's number 6.023 × 1023 of particles.
Given,
One atom of an element weights 1.792 × 10-22 g
Thus, 1 atom weights = 1.792 × 10-22 g
6.023 × 1023 atoms will weight = 1.792 × 10-22 × 6.023 × 1023
= 1.792 × 6.023 × 10
= 108
