show how to get to the final answer of 4.47×10^8 mol sb please

17. Locate the element antimony in the periodic table. Would this element be classified as a metal, nonmetal, or metalloid? Antimony is used in alloys with lead or t is combined with other substances to make fireproof fabrics, is mixed with some types of glass and ceramics, and serves as the active component of some medicines, Antimony however, does have some toxic properties. One way to obtain it is as follows: d sb2s3 3 Fe 3 Fes +2 sb metallo. Balance this equation. The annual worldwide production of antimony is approximately 6.00x 104 tons. How many moles of antimony is this x no/ sb

Explanation / Answer

Sb2S3   + 3 Fe   -------------> 3 FeS + 2 Sb

mass of antimony = 6.00 x 10^4 tons

1 ton = 907185 g

6 x 10^4 tons = 5.443 x 10^10 g

molar mass of Sb = 121.7 g/mol

moles = mass / molar mass

          = 5.443 x 10^10 / 121.7

          = 4.47 x 10^8 mol Sb
