Given the empirical formula NO with a molar mass of 59.98 g/mol, what is the molecular formula for this compound

N₂O₂

Explanation:

The empirical formula NO tells us that the number of Nitrogen atoms will always be equal to the number of Oxygen atoms.

The molar mass of the simplest compound, NO, would be:

We divide the molar mass of the problem compound by the molar mass of the simplest compound:

This means we multiply the empirical formula times 2:

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.
