CHEM 1122 Lecture Notes - Lecture 4: Hydrogen Peroxide, Chemical Formula, Unified Atomic Mass Unit
Document Summary
Sodium is an important dietary mineral that we eat in food, primarily as sodium chloride (table salt) regulates body fluids and eating too much of it can lead to high blood pressure - increases high attack and stroke. Chemical composition is important for addressing dietary sodium intake and many environmental issues. Converting between grams and moles of an element. Converted between moles and atoms -> now we need one more conversion factor to convert from the mass of the sample to the number of atoms in the sample. The mass of 1 mol of atoms of an element is its molar mass. The value of an element"s molar mass in grams per mole is numerically equal to the element"s atomic mass in atomic mass units. Avogadro"s number = the number of atoms in a mole, number of atoms in exactly. *the mole concept - converting between grams and moles. *the mole concept - converting between grams and number of atoms.
