How many grams of bromine gas is in 2.03x10^32 atoms of bromine gas?

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
