Question

How many ml's of a 5% (W/V) solution will be necessary to make 6 oz of a 1:200 solution?

A. 18 ml
B. 44 ml
C. 253 ml
D. 427 ml

Answer 1

To make 6 oz of a 1:200 solution using a 5% (W/V) solution, you would need 44 ml.

Step-by-step explanation:

To solve this problem, we can use the formula:

Concentration1 x Volume1 = Concentration2 x Volume2

Let's plug in the given values:

5% (w/v) x Volume1 = 1:200 x 6 oz

Converting the unit of 6 oz to mL:

6 oz x 29.6 mL/1 oz = 177.6 mL

Solving for Volume1:

0.05 x Volume1 = 1/200 x 177.6 mL

Volume1 = (1/200) x (177.6 mL/0.05) = 44.4 mL

Therefore, option B: 44 ml is the correct answer.
