Answer #1

Q4. For sample 3, [SCN-]0 = 0.000600 M

Q5. For sample 4, [SCN-]0 = 0.000800 M

Q6. For sample 5, [SCN-]0 = 0.00100 M

Explanation

For sample 3,

[SCN-]0 = M * (V / VTotal)

where M = molarity of KSCN = 000200 M

V = volume of KSCN = 3.00 mL

VTotal = 10.00 mL

Substituting the values,

[SCN-]0 = (0.00200 M) * (3.00 mL / 10.00 mL)

[SCN-]0 = (0.00200 M) * (0.300)

[SCN-]0 = 0.000600 M
