Answer 1

41.3 ml of 0.110 M NaOH salution mean the the malarity of Nachsolution is 0.110 Moles per litre / 1000ml solution. jie 1000 ml solution LL ml solution contains contains 0.110 0.110 1000 moles of NaOH moles of NaOH and; 41.3 ml solution contains 0.110 x 41.3 males. 10oo --- 0.004543_males of Nall. Helly + NaOH Naclou + H₂O (1 mole) (imple) According to balanced chemical equation Naohº neutralise_ 1 mole of Hillby. 1 mole So, mode NaOH 9 9 иіле — 1 тоlе of HO4 0.00 4 543 mole NaOH require - 0.0045 43 moles HUO :: 35.0 mL sample_of_Hlldy contains 0.0045 43 muales _of_Ноу.

so, concentration of HClO is Malarity, M = moles volume in litre - -- : 0.00 45.43 mole 0:0354 = 0:1298M ar = 0.130 M. [: 1000 ml = 14]
