tolong bantuannya nomer 48? apakah benar jawabannya

Ca(OH)2 -> Ca2+ + 2OH-
1 mmol 1 mmol 2 mmol
NaOH -> Na+ + OH-
4 mmol 4 mmol 4 mmol

M = 2 + 4 / 10 + 40 = 6 / 50 M

6/50 . 50 = M2 . 250
M2 = 0.024 M (D) -> Jawab

[tex]\displaystyle \text{M}=\frac{n\text{Ca(OH)}_2+n\text{NaOH}}{V}\\\text{M}=\frac{2\cdot0,1\cdot10+0,1\cdot40}{250}\\\text{M}=\frac{2+4}{250}\\\text{M}=\frac{6}{250}\\\text{M}=\frac{24}{1000}\\\boxed{\boxed{\text{M}=0,024\,\text{M}}}[/tex]
