Answer to Question #287683 in General Chemistry for gan

Question

zinc and sulfur react to form zinc sulfide. if 6.00g of zinc react with 9.00g of sulfur, how many grams of zinc sulfide will form

Answer 1

8Zn + S8 - 8ZnS

6g × 1mol Zn/65.38g = 0.0918molesZn

9g× 1mol S8/256.52g=0.0351moles S8

0.0918molesZn × 8moleZnS/8moleZn

=0.0918moleZnS

0.0918moleZnS × 97.445g/1molZnS

= 8.9455 grams of ZnS
