A sample 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 moles 40.00 moles 160.0 moles 6,400 moles

Respuesta :

The number of moles the sample of sodium hydroxide (NaOH) will contain is 4 moles.

How we calculate moles?

Moles of any substance will be calculated by using the below formula:
n = W/M, where

W = given mass

M = molar mass

Given mass of NaOH = 160 g

Given molar mass of NaOH = 40 g/mole

On putting these values on the above equation, we get

n = 160 / 40 = 4 moles

Hence, required moles is 4 moles.
