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 :

4 moles of NaOH is present in the given 160 grams of NaOH.

How we calculate moles?

Moles of any substance will be calculated as:

n = W/M, where

W = given mass of NaOH = 160 grams (given)

M = molar mass of NaOH = 40 g/mole

Moles of NaOH is calculated as:

n = 160g / 40g/mol = 4 moles

Hence, moles of sodium hydroxide (NaOH) is 4 moles.
