Question

How many moles of Sis2 will be produced if 3.25 grams
CuS is completely reacted?
Si + 2Cus → 2Cu + Sis2​

Answer 1

Answer:

    0.000170 mol

Explanation:

This problem can be solved using dimensional analysis:

3.25g CuS × $\frac{1 mol CuS}{95.61 g CuS}$ ×$\frac{1 mol SiS_{2} }{2 mol CuS}$ = 0.000170 mol $SiS_{2}$
