Question

Quantos mols equivale 160 g de NaOH ?

Answer 1

MM do NaOH = 23 + 16 + 1 = 40g/mol 


1mol ---------------------- 40g 

x mol --------------------- 160g 


x = 160 / 40 

x = 16 / 4 

x = 4 mols

Answer 2

MM do NaOH = 23 + 16 + 1 = 40g/mol 
1mol ---------------------- 40G
x mol --------------------- 160g 
x = 160 / 40 
x = 16 / 4 
x = 4 mols
