Question

How many moles of Sis2 will be produced if 3.25 grams

CuS is completely reacted?
Si + 2Cus → 2Cu + Sis2​

Answer 1

0.000170 mol

Step-by-step explanation:

This problem can be solved using dimensional analysis:

3.25g CuS ×
`(1 mol CuS)/(95.61 g CuS)` ×
`(1 mol SiS_(2) )/(2 mol CuS)` = 0.000170 mol
`SiS_(2)`
