✨ 最佳解答 ✨ avocadocompany 約3年以前 左: 5.2g 中只有36.5%是鹽酸所以總重要乘0.365然後除HCl的分子量(1+35.5)會得到鹽酸的莫耳數乘上每莫耳可以解離出的氫離子為1個 avocadocompany 約3年以前 右: 濃度為一公升水含有0.5莫耳的氫氧化鈉取其中的x公升又每莫耳可以解離1個氫氧根離子所以0.5mol×x公升×1個OH=左式 留言

(A)為什麼要放在同一個根號裡？
不能拆開來分別算完[OH-]再加起來？ - 1](https://d1e9oo257tadp1.cloudfront.net/uploads/qa_question_image/file/1755980/thumb_l_webp_ED5CBF12-E478-41E8-84BE-58DB409F14D0.webp?Expires=1750063352&Signature=Ad-u~h7TknGpYVfPFc1lMOAR6RQ3VVI7Pnox0hkNxrd3JBG2cEfSQPSUVsIl5eJ~sU~lM-8wIiOk1vwoFdKfYAxicNIE4Ienf1Lr~8NE3SUWI04GceaeDj2NEocGRNzRcq23NRNtZJLAvHLq9IXh0gLaUcj2P7uH706uOZnGJN7-QqhRVtQUISdKqnUfGnuLXlZiAYt7wt1vZUpdb6xrjAKTK3ryVqXaRgcNi0mV86r3AP7uFKy9Oj1gP3G73aNadeDf23tzfzpGe0CfkmUGDUK7l8uWu-zdwCx5Q2EP4oT3J0wCj1mBgHhiEWfsY9~E8kBAlKf~e9OqJz6oA8cgng__&Key-Pair-Id=K2W722D70GJS8W&Expires=1750063352&Signature=bFEX5iTt9O~FKyjhDjrZPpJHAAEvrnzDTa6BZy72N6nsooXSEJL~3iQMrLOVyPcy5Yl496V1DwGlaXETKbzPTHETJ9Vq4~Wx7dLd7SBE7SrMB8SaH76UQpCvZhXWJxM8LoQ9Z1I5C4edsrPXYveCaGPB8uIJ~0wRnBuP-G4EiWF1f2sK7QxnSQRApvXGA9CW8vf1xU7hLhD~P8ErUsiHNOMBNbJ9pAqwmeop~bbQKsCFf1KJYLercemzN5elpCIedKHWJuSN11zXfvClXVbekda8KHn4hOYI9NzYmlYTwKcSv66AhFEfBl9JnZ0RWPhH4hpWH7qA1PNJeXr0ELSl7A__&Key-Pair-Id=K2W722D70GJS8W)
