Answer:
a. Response factor is 0.1775
b. 11.7mM of X in the original unknown
c. 5.85mM is the concentration of X in the diluted solution
Explanation:
a. The equation to find response factor is:
F = AreaX*[S] / AreaS*[X]
Where Area of X our sample and S the internal standard whereas [] represent the concentration of each one.
Replacing:
F = 3497*1.72mM / 9997*3.39mM
F = 0.1775
c. The concentration of S is:
8.47mM * 1.00mL / 10.0mL = 0.847mM
Replacing:
0.1775 = 5428*0.847mM / 4431*[X]
[X] = 5.85mM is the concentration of X in the diluted solution
b. The concentration of X in the original unknown is:
5.85mM * (10.0mL / 5.00mL) =
11.7mM of X in the original unknown
