INFO TO USE TO CALCULATE QUESTIONS:
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
