Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry deals with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds. Chemistry also involves understanding the properties and interactions of individual atoms and molecules for use in larger-scale applications.

In chemistry and physics, matter is any substance that has mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles and objects that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound. Matter exists in various states (known as phases) that are defined by various physical properties, such as state of matter, phase, shape, and density. The Standard Model of particle physics and the general theory of relativity describe fundamental particles and the fundamental forces acting between them that control the structure and dynamics of matter.

Hi. So this question is about cock upright Chalco pyrite, which is a principle or of copper. And they says it contains 34.63% copper by mass. And so they want you find how many grams of copper can be obtained from 5.11 times 10 to the third kilograms of Chalco. Pyrite. Okay, so pretty simple question. Just all we need to do here is multiply the, um, multiply the the mass of the or by the percentage of copper. And then, of course, we convert that two grams. Okay, so 5.11 times 10 to the third kilograms of the or and then we need to, uh or kilograms for and then multiply this by the percentage. So 30 for 0.63 over 100. Okay. And then we'll get a new unit here, which is copper for 100 war. It's a little ratio here. This will cancel out, and then we should get one top 10 to 30 tires. 34.63 over 100. You should get one point seven seven times 10 to the third kilograms of copper. Now we need to convert this two grams because they do ask for it in grams. How do we convert this? Two grams? How many grams are in a kilogram? 1000 writes. We multiply this by 1000. So 1000 grabs kilogram and you get 1.77 times 10 to the sixth grams copper. Okay, so pretty simple. And, um, pretty easy. Just a little bit of percentages for you. And you hope this was helpful. And thank you for listening.
