Question

calculate the molecular mass of the CH3COONa(C-12,H-1,O-16,Na-23)​

Answer 1

Answer:

The molecular mass of CH3cooNa is $82$.

Explanation:

CH3cooNa

$12+1\times3+12+16+16+23$

$12+3+12+16+16+23$

$=82$

Use the mass listed in the Periodic Table or Atomic Weight Table to get the atomic mass for each element. To calculate the molecular mass, multiply the subscript (number of atoms) by the atomic mass of the relevant component and add the masses of all the other elements in the molecule. Refers to the group of a substance in a mole and is used to describe the group that results from adding the atomic masses of all the atoms in a molecule—also referred to as molecular weight It establishes the mass of each molecule. Kilograms are the atomic and molecular mass units in the SI system.
