Question

How many moles of sulfur are in 53.7 grams of sulfur?

Answer 1

1.67 moles (find this by dividing 53.7 by the gram formula mass of sulfur, which is about 32.1)

Answer 2

NO.OF.MOLES= MASS/ATOMIC MASS
THE ATOMICITY OF SULPHUR IS 8 AND ITS MASS NUMBER IS 32.
SO, THE ATOMIC MASS IS 256
NO.OF.MOLES= 53.7/256
= 537/2560
= 0.2097
