What is an atomic mass of NaOH ?

Answer 1

Well, what is the molar mass of sodium hydroxide....?

The molar mass of sodium hydroxide is #40.00*g*mol^-1#...

But this, BY DEFINITION, specifies the mass of #"Avogadro's number"# formula units of sodium hydroxide....i.e. #6.022xx10^23*"formula units of sodium hydroxide per mole."#

Thus, the quotient provides the mass of ONE formula unit of sodium hydroxide.

#"mass"_"one formula unit of NaOH"=(40.00*g*mol^-1)/(6.022xx10^23*mol^-1)#

#=6.641xx10^-23*g#...

The atomic mass of NaOH is calculated by adding the atomic masses of each individual atom in the compound.

Na (Sodium) has an atomic mass of approximately 22.99 g/mol. O (Oxygen) has an atomic mass of approximately 16.00 g/mol. H (Hydrogen) has an atomic mass of approximately 1.01 g/mol.

Adding these together gives:

22.99 g/mol (Na) + 16.00 g/mol (O) + 1.01 g/mol (H) = 40.00 g/mol

Therefore, the atomic mass of NaOH is approximately 40.00 g/mol.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
