Question

What is the weight of NaOH present in 20cc of a 2 molar solution?​

Answer 1

Answer:

Explanation:

If pH =13, the pOH =14−13=1

If pOH =1,[OH

−

]=10

−

 pOH =0.10

Since NaOH=0.10M,then:

0.10mol/L×0.250L=0.025molNaOH

Mass of NaOH=0.025mol×40g/mol=1gNaOH

If pH =13, the pOH =14−13=1

If pOH =1,[OH

−

]=10

−

 pOH =0.10

Since NaOH=0.10M,then:

0.10mol/L×0.250L=0.025molNaOH

Mass of NaOH=0.025mol×40g/mol=1gNaOH
