The density of water is 1.00 g/mL at 4°C. How many water molecules are present in 2.66 mL of water at this temperature?

it should be p1 v1 = p2 v2

yes it is balanced

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.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
