【英語ですみません】3. a. b. c. がわかりません。 mole と amu、そしてこの単位を使うときのmolecules と atom の概念（？）がわかりません。 b. はやってみたのですが、他は問題がよくわかりません…どなたか説明お願いします🙇‍♂️🙏

Complete the following exercises to help you solidify your understand the utility of moles: The conversion factor given in the back of your book isl amu = 1.66 × 10-2/ kg. 10o0g This can be written as 1.66× 10-27 Kg ("kilograms per amu"). × Tkg amu 1. Change this conversion factor to grams per amu. 1,60xl0/amu 2. To get the number of amu per gram (the inverse), take the inverse of the number answer to #1 (divide 1 by that number). WRITE THE UNITS. -- do you recognize this number??! 3 amu kg 0gadols number 3. Since you have a conversion factor in amu(#1), you can convert from a mass in amu to one in grams. Do the following in order to demonstrate to yourself again what a mole is: a. How much does 1 molecule of SO, weigh in amu? b. How much does 1 molecule of SO, weigh in grams? 32,07+ 162)- 69.07g c. How muchdo 6.022 × 1023 (one mole of) SO, molecules weigh in grams? emoie n ftoe

So water is not solid, for I can't take up a pinch of it in my fingers as I can with sand. 訳をお願いします。

これって違うものじゃないんですか？ 回転できなくないですか？
