Chlorhexidine gluconate is available in different products in concentrations of 4% w/v and 0.12% w/v. How many milliliters of the more dilute product may be prepared from each fluidounce of the more concentrated product

From each fluidounce, 985.78 milliliters of the more dilute product can be produced.

Explanation:

From the given information:

4% w/v = 4g of solute in 100 mL of solution

0.12% w/v = 0.12g of solute in 100 mL of solution

Since 1 fluidounce = 29.5735 ml

∴

100 mL of solution contains 4g of solute

29.95735 ml will have

= 1.18294g solute

Thus, 1 fluidounce contains 1.18294g solute

So, for the dilute solution, 0.12 g solute yields 100 mL solution

∴ 1.18294g will have

= 985.78 ml
