插入表格时出现浮动错误

Question

说实话，在使用 Latex 方面我完全是个新手，但我真的很享受它在科学和数学课程中做笔记时的实用性。然而，我现在试图将表格插入阴影区域，但收到一条错误消息，提示“！LaTeX 错误：浮点数丢失。”

有人能解释一下我的编码哪里错了吗？我本来创建了一个表格，但以为我打错了，于是我谷歌了一下教程中的表格并将其粘贴进去，但仍然收到错误。

In order to study hydrogen halide decomposition, a researcher fills an evacuated 2.00L flask with 0.200mol of $HI$ gas and allows the reaction to proceed at 453$\degree$C.\\
At equilibrium, $[HI]=0.078$mol. Calculate $K_c$.\\

First we need to convert mol to concentration: $[HI]=\frac{0.200mol}{2.00L}=0.100M$
Now we need to use an ICE table:

Answer 1

使用[H]来自的选项float，使表格不浮动（然而，这可能会产生大的空白）或者用\captionof[table{...}`替换table环境 + 。\vationcenter +

我加载了caption包以便在标题和表格之间留出合理的间距，titlesec 并选择[center]避免输入所有这些center环境，siunitx以便在输入单位时有正确的间距。

In order to study hydrogen halide decomposition, a researcher fills an evacuated \SI{2.00}{\L} flask with \SI{0.200}{\mol } of $HI$ gas and allows the reaction to proceed at \SI{453}{\celsius}.\\
At equilibrium, $[HI]=\SI{0.078}{\mol}$. Calculate $K_c$.\\
