The answer is A. Here is why:
500 micrograms is 0.5. You need 0.6. You would fill up the syringe to 1ml for the 0.5 and the rest are too high
Answer: 30 meq
Explanation:
We know that 1 gallon = <u>3.785 Litres</u>
1 litre = <u>1000 milliliters</u>
1 gallon = <u>3785 ml</u>
<u>Concentration = weight/volume </u>
= 565/3785
= 0.149 g/ml
= 149 mg/ml
Multiplying with 15 ml we get
= 149*15 = <u>2235 mg</u>
<u>The atomic weights of:</u>
Potassium (K) = 39
Chlorine (Cl) = 35.5
Finding the equivalent weight of Kcl = 39 + 35.5 = 74.5
So, 1 equivalent of KCl is 74.5 g
= 2235 mg * 1 meq/74.5 mg = 30 meq K+
Therefore, there are 30 milliequivalents of K in 15 ml of this solution
