Calculate the molar mass of sulfur in a sample that consists of 91.65% 32S (molar mass 31.97 g/mol), 2.4% 33S (molar mass 32.97 g/mol), 5.95% 34S (molar mass 33.97 g/mol). Answer in units of g/mol.

32.11 g/mol

Explanation:

Given;

32S => 91.65%, 31.97g/mol

33S => 2.4%, 32.97g/mol

34S => 5.95%, 33.97g/mol

The molar mass of sulfur in the sample is the weighted average of the molar masses of its isotopes based on the percentage abundances.

i.e

molar mass = ( x 31.97) + ( x 32.97) + ( x 33.97)

molar mass = (0.9165 x 31.97) + (0.024 x 32.97) + (0.0595 x 33.97)

molar mass = (29.30) + (0.79) + (2.02)

molar mass = 32.11g/mol

Therefore the molar mass of sulfur in the sample is 32.11 g/mol

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
