Answer:

0.2 ml

Explanation:

Stock dilution is done by using the formula C1V1 = C2V2 where,

C1V1 = Start volume and concentration

C2V2 = Final volume and concentration

Here,

C1V1 = C2V2

5 mg/ml * V1 = 0.1 mg/ml * 10 ml

V1 = ( 0.1 * 10 ) / 5 ml

    = 1/5 ml

    =  0.2 ml

So 0.2 ml of nitroglycerin stock is needed to make the final solution.
