Calcular la fraccion molar de NaClO en una solucion blanqueadora comercial que comtiene 3,62% en masa de NaClO en agua
muminat

<em>Calculate the molar fraction of NaClO in a commercial bleach solution that contains 3.62% by mass of NaClO in water</em>

<em />

<h3>Further explanation</h3>

convert mass to mol

mol NaClO (MW=74.5 g/mol) :

\tt \dfrac{3.62}{74.5}=0.0486

mol H₂O (MW= 18 g/mol) :

\tt \dfrac{96.38}{18}=5.354

Total mol :

0.0486 + 5.354 = 5.4026

mol fraction of NaClO :

\tt X_{NaClO}=\dfrac{0.0486}{5.4026}=0.009=9.10^{-3}
