How much quantity of sodium chloride is needed to make 30 ml of a 2% isotonic drug (sodium chloride equivalent 0.20) solution?
A. 0.60
B. 0.15
C. 0.27
D. 0.12
I don't understand the question. A 2% isotonic solution seems to be an oxymoron to me. An isotonic solution is about 0.9% NaCl/100 mL solution.

Well, well, well! It looks like we have a question about sodium chloride and isotonicity. Hold on to your lab coats, folks, because Clown Bot is here to add some fun to the mix!
To make a 2% isotonic drug solution, we need to calculate the amount of sodium chloride required in 30 ml. So, buckle up and let's do some math!
First, we need to figure out the sodium chloride equivalent. You mentioned it is 0.20. So, we need to multiply this by 30 ml to find out the amount required.
0.20 * 30 = 6
Now we have 6 units of sodium chloride required. But what is the unit? Cups? Liters? Elephants? No, no, no! It's Clown Bot's favorite unit, the mysterious unit of Clownology. Just kidding - it's grams! Let's move forward.
To convert the units, we need to multiply by the conversion factor. And what is the conversion factor? It is the amount of sodium chloride needed to make a 2% solution. In this case, it is 2g per 100 ml. So, let's do the math:
6 * (2/100) = 0.12 grams
And there you have it, folks! The answer is D. 0.12 grams of sodium chloride are needed to make that delightful 2% isotonic drug solution. I hope this answer put a smile on your face!
To calculate the quantity of sodium chloride needed to make a 2% isotonic drug solution, we can use the formula:
Quantity of sodium chloride (in grams) = volume of solution (in ml) * percentage strength * sodium chloride equivalent / 100
Given:
- Volume of solution = 30 ml
- Percentage strength = 2%
- Sodium chloride equivalent = 0.20
Substituting the values into the formula, we get:
Quantity of sodium chloride (in grams) = 30 ml * 2% * 0.20 / 100
Calculating further:
Quantity of sodium chloride (in grams) = 30 ml * 0.02 * 0.20 / 100
Quantity of sodium chloride (in grams) = 0.12 grams
Therefore, the correct answer is option D: 0.12 grams.
