Video Transcript

this video, we're gonna walk over just how to convert Grams to moles. Through sick of ours problem. We're going come say that we have 77.4 grams calcium. We understand that calcium has actually an atom mass of 40.78 start our equation. We recognize that we have actually 77.4 grams the calcium and we have to multiply the by miscellaneous to get rid of grams and get 2 moles. Because we have actually an atom mass that 40.78 we understand that 40.78 moles of calcium, grams that calcium equal to one mole of calcium. Therefore, we will play one mole that calcium end 40.78 grams through 77.4 grams to acquire mold. We recognize this because grams of calcium on the ideal side crossed out grams that calcium on critical night. We're left through moles. Using basic multiplication, we uncover that 77.4 grams that calcium sequel toe 1.93 moles

Intro to Chem - advent

Chemistry is the scientific research of matter, especially its chemical reactions, but also its composition, structure and also properties. Chemistry deals with atoms and also their interaction with various other atoms, and specifically with the nature of chemistry bonds. Chemistry additionally involves knowledge the properties and interactions of separation, personal, instance atoms and molecules for use in larger-scale applications.


Classification and Properties of issue

In chemistry and physics, matter is any kind of substance that has mass and takes up space by having actually volume. All day-to-day objects that deserve to be touched are at some point composed the atoms, i m sorry are made up of connecting subatomic particles, and also in everyday and scientific usage, "matter" generally consists of atoms and anything consisted of of them, and any particles and also objects the act together if they have actually both remainder mass and volume. However it go not incorporate massless particles such together photons, or other energy phenomena or tide such together light or sound. Matter exists in miscellaneous states (known together phases) that are defined by miscellaneous physical properties, such as state of matter, phase, shape, and also density. The Standard model of bit physics and the general theory of relativity describe an essential particles and also the an essential forces acting between them that manage the structure and also dynamics that matter.
