Consider that you have a 100 mm stock solution and you need to prepare 10 ml of a 30 mm solution. how many milliliters of the stock solution do you need? ml how many milliliters of deionized water do you need? ml

V₁ = 3.0 mL

V(H₂O) = 7 mL

Explanation:

Given data

In order to determine the volume of the stock solution, we will use the dilution rule.

C₁ × V₁ = C₂ × V₂

100 mM × V₁ = 30 mM × 10 mL

V₁ = 3.0 mL

The volume of deionized water required is:

V(H₂O) = 10 mL - 3.0 mL = 7 mL

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
