Mass of sodium + nitrogen +oxygen+ oxygen+ oxygen =

Mass of sodium + nitrogen +oxygen+ oxygen+ oxygen = =85 g/mol

Explanation:

Molar mass is the mass of 1 mole of the substance and its unit is g/mol

We find the molar mass by just adding atomic mass of the elements present in the chemical formula of the compound

For example  

Atomic mass of H is 1.008 (approximately 1)

Atomic mass of S is 32

Atomic mass of O is 16

There are 2, H atoms 1, S atom and 4, O atoms

So, the molar mass of the compound will be

The question says 1, Na  

1, N and  

3, O

So the chemical formula we get is

The molar mass of the compound is

=85 g/mol (Answer)

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.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
