What is the formula mass of nitric acid?

Answer 1

Naomi Aronson

#HNO_3#; this has a molar mass of #(1.00794+14.01+3xx16)# #g*mol^-1#

Typically this is supplied as a 68-70% solution, with a concentration of approx. #15# #mol*L^-1#.

The formula mass of nitric acid (HNO3) is calculated by adding the atomic masses of its constituent atoms: hydrogen (H), nitrogen (N), and oxygen (O). The atomic masses are approximately 1.008 u for hydrogen, 14.007 u for nitrogen, and 15.999 u for oxygen. Therefore, the formula mass of nitric acid is approximately 63.012 atomic mass units (u).
