Atablet of pain be gone aspirin, which had a mass of 1.213 g, was pulverized and 1.159 g were dissolved in 10.0 ml of ethyl alcohol and 25.0 ml of di water. the titration of this solution with 0.1052 m naoh required 15.62 ml to reach the phenolphthalein endpoint. determine the moles of naoh that reacted with the acetylsalicylic acid.

Moles of NaOH that reacted:

Explanation:

During the  titration, all moles of NaOH added in the solution, react with the acetylsalicylic acid neutralizing each other.

The titration required 15.62 ml (0.01562 L) of the 0.1052 M NaOH solution. The moles of NaOH in that volume are:

output?

explanation:

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.
