Answer:
(c) 108.36 is the correct answer
Explanation:
given mass/MOLECULAR MASS= no of atoms given/ avagadro no
1.8× 10^-22/ X = 1/6.022×10^-23
X = 108.36 g

Answer:
108.36 is the correct answer for this question
Explanation:
1 atom of an element = 1.8×10^-22 g
Now,
mass of one atom = GAM/ NA
1.8×10^-22 = GAM/ 6.022×10^23
GAM= 108.396 g
GAM- gram atomic mass
NA- Avogadro's number
