Answer:
1Calculate the initial number of moles of CuCl2:
Moles
=
Molarity
×
Volume
Moles=Molarity×Volume
Moles
=
4.00
mol/L
×
2.00
L
Moles=4.00mol/L×2.00L
Moles
=
8.00
mol
Moles=8.00mol
2Convert the final volume to liters:
3500
mL
=
3500
×
1
0
−
3
L
=
3.50
L
3500mL=3500×10
−3
L=3.50L
3Calculate the final concentration of CuCl2 after dilution:
Molarity
=
Moles
Volume
Molarity=
Volume
Moles
Molarity
=
8.00
mol
3.50
L
Molarity=
3.50L
8.00mol
Molarity
=
2.29
M
Molarity=2.29M
