#7754.9g#
If the sample was measured in grams, we would first need to convert it to moles and then determine the amount of titanium. Because we already have the sample in a molar quantity, the moles of titanium is simply the formula ratio – 6 moles of titanium per mole of compound.
So, we have #6 xx 27 = 162# moles of titanium. Converting this to mass from the gram molecular weight, we obtain is
#162 xx 47.87 = 7754.9g#
The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g = 
the percentage of heaviest Sn is 5.80%
So the total atoms of
= 5.80% X 
Total atoms of
=
atoms
the mass of
will be =
