想請教計算方法，目前求得莫爾比但後續處以0.18（化整數）時感覺很怪，題目要求120克pan的經驗式，但我化完整數後光是C+H前兩項的質量就會超過120克了，想請教各位如何計算

C z Hz N O S o f 3.44 Peroxyacylnitrate (PAN) is one of the components of smog. It is a compound of C, H, N, and O. Deter- mine the percent composition of oxygen and the empirical formula from the following percent composition by mass: 19.8 percent C, 2.50 percent H, 11.6 percent N. What is its molecular formula, given that its molar mass is about 120 g?

想請問這題的醚和胺的沸點可以如何排序？ 因為我印象中氫鍵的影響比極性大，因此不了解為什麼胺的沸點比醚小 謝謝🙏

1. Compare the products formed by the reaction formed when the following compound reacts with Br, in the presence of an organic solvent versus water.

我想請問 原本fn只在所有compacts上一致收斂 D裡面會不會也包含沒辦法closed and bounded的部分 但我最後要證明的卻是在整個D上f都連續 這樣①③的選擇會不會只證明f在D中的任何compacts連續呢 如果會的話要怎麼改善證明 （高微證明小白求解..

(1 point) The manager of a large apartment complex knows from experience that 120 units will be occupied if the rent is 300 dollars per month. A market survey suggests that, on the average, one additional unit will remain vacant for each 10 dollar increase in rent. Similarly, one additional unit will be occupied for each 10 dollar decrease in rent. What rent should the manager charge to maximize revenue?
