How many moles of NaOH are in a 75.89g sample? (mass= 40.01 g) (Show your work)

1.896 moles of NaOH> 1.90 moles

Explanation:

75.89 g of NaOH  |  1 mole of NaOH  

                             |  40.01 g NaOH                = 1.896 > 1.90 moles of NaOH

(75.89 g NaOH/ 40.01 g NaOH = 1.896 > 1.90 moles of NaOH
