Asample of sodium hydroxide (naoh) has a mass of 160.0 g. the molar mass of naoh is 40.00 g/mol. how many moles of naoh does this sample contain? 4.000 40.00 160.0 6,400

Answer : The number of moles of NaOH contains, 4.000 moles

Solution : Given,

Mass of = 160.0 g

Molar mass of = 40.00 g/mole

Now we have to calculate the moles of .

Now put all the given values in this formula, we get the moles of NaOH.

Therefore, the number of moles of NaOH contains, 4.000 moles
