purpose of the mole

 Since atoms are very small and very difficult to individually measure, we use mass to estimate the number of atoms and vice versa. To help with this, a measurement called the mole is used to help count atoms. With the use of the mass spectrometer, the number, 6.022 x 10^23 was found to be the most sufficient for chemistry purposes. The number got its name, Avogadro's Number, after his countless achievements and discoveries within chemistry. One mole of something is equal to 6.022x10^23 amount of that item, or 6.022 hexillion. Since atoms are very small, a bulk amount of them, in this case, a mole, is used to measure a sample of atoms. Like a couple of bottles is 2 bottles, and a mole of bottles is 6.022 hexillion bottles. Even on the periodic table of elements, there exists something called a molar mass, which is the mass of a mole rather than just a single atom so atoms can be measured as a sample and not individually. 6.022 hexillion is a very large number and difficult to imagine its sheer size. Small objects, like dice or erasers, can cover the whole earth multiple times if there is a mole of them. This puts into perspective how small atoms really are, and why moles are used to calculate and measure them. More than a mole would be too big of a sample and less than a mole would be too small, which makes the mole an optimal amount to measure.

    I like how you explained the topic in such detail! It really made it easy for the reader to follow along!

    I like how you wrote your passage in an informal way but still described really well just as the original one

Polite vs Impolite

I think something common with human behavior is that people change their attitude based on the person they are interacting with. A highly respected individual would receive more respect than just a random person. An example of this is a doctor. A doctor gets the title "Dr." behind their name (everyone else just has "Mr." or "Ms." or "Mrs."), and they are addressed this way, in respect, and have a high status in society. Due to their elite status, people are usually polite to them because they feel inferior to the doctor. But there are also other situations where the need to use polite or impolite language changes. Adding on to the examples of respected individuals, people tend to be more nice and polite to people who are older than them, like their teachers, bosses, and even their parents and grandparents. Other than just being polite, if there's someone who's superior to you, you feel the pressure to impress them. For example, if you...

Invisible Lives, Visible Stories

In  Sweat , Lynn Nottage casts a spotlight on factory workers and the problems that come with it. Nottage talks about global events, with one notable example being the impact of NAFTA. NAFTA created free trade between Canada, USA, and Mexico which caused many people to lose their jobs because now they could be manufactured in different countries without tariffs when being exported. Before I read  Sweat  I didn't know about NAFTA or the effect it had on factory workers, but Nottage uses  Sweat  to publicize this problem. "You could wake up tomorrow and all your jobs are in Mexico, whatever, it’s this NAFTA bullshit" (Nottage). Even the characters in  Sweat  don't know much about NAFTA, which shows the unfamiliarity of this large change. Nottage also highlights the problems that arose between people and friends because of people being laid off. At Jessie's birthday party, Cynthia talks about how she got a promotion, and Tracey gets mad and jealous becaus...

My name

I have a very unusual name, and I don't know anyone else who has it. My family calls me by the nickname "Thanesh," which sounds weird, so whenever I introduce my name to anybody, I just go by my actual name. Because of this, my name is mispronounced all the time. A key example of this is at the beginning of the school year, when your teachers take attendance and learn everyone's name for the first time. My name gets mispronounced almost always, and I always have to correct them with the right pronunciation. This is something that I've gotten used to over time, and I'm always prepared to correct anyone who mispronounces it, and it doesn't really bother me. This experience is similar to Dumas' piece, but once people get the pronunciation right, they don't mess up afterwards. But one time I don't feel the need to correct the pronunciation of my name is when I have a substitute teacher. These substitute teachers pronounce it in the most atrocious w...
