Answer: this question might have a mistake where the number of atoms should be 2.03 x 10^23 rather than 2.03 x 10^32. The answer for 2.03 x 10^32 is 53.88 x 10^9 grams
While that of 2.03 x 10^23 is 53.88 grams
Explanation:
We have that number of mole = reacting mass/molar mass and also
Number of moles = number of atoms/avogadros number;
Equating both yields reacting mass /molar mass = number of atoms / avogadros number;
X/159.8= 2.03 x 10^23/6.02 x 10^23
X = 53.88 grams
