Question

2 moles of zinc reacts with a cupric choloride solution containing 6.023×1022 formula units of cucl2 calculate the moles of copper obtained

Answer 1

Answer:

2 moles of Copper would be obtained.

Answer 2

$zn + cu2 = zacl2 + cu$

1 mole zn + 1 mole cucl2= 1 mole cu

$2 \: mole \: of \: zn + 6.023 \times {10}^{22} \: cucl2 = what$

$2 \: mole \: of \: zn + 0.1 \: mole \: of \: cucl2 = what$

1 mole Cucl2 =1 mole of cu

0.1 mole of Cucl2 = cu (x)

$x \times 1 = 0.1 \times 1$

x= 0.1 mole of cu
