Sodium hypochlorite (#NaClO#) is the active ingredient in household bleach. What is the formula mass of sodium hypochlorite?

Answer 1

Peyton Adams

#NaClO# has a formula mass of #74.44*g*mol^-1#.

And formula mass is simply the sum of the component atomic masses: #(22.99+35.45+15.999)*g*mol^-1=??#

Naomi Aronson

The formula mass of sodium hypochlorite (NaClO) is calculated by adding the atomic masses of sodium (Na), chlorine (Cl), and oxygen (O) together.

Atomic mass of Na = 22.99 u Atomic mass of Cl = 35.45 u Atomic mass of O = 16.00 u

Formula mass of NaClO = 22.99 + 35.45 + 16.00 = 74.44 u
