I want to make a solution that contains 1. You do not have a balance calibrated in moles, but you do have one calibrated in grams. If you know the relationship between moles and the number of grams in a mole, you can use your balance to measure out the needed amount of material. Molar mass is defined as the mass of one mole of representative particles of a substance. One molecule of carbon dioxide consists of 1 atom of carbon and 2 atoms of oxygen.

Molar mass potassium

Potassium is a chemical element ; it has symbol K from Neo-Latin kalium and atomic number It is a silvery white metal that is soft enough to easily cut with a knife. It was first isolated from potash , the ashes of plants, from which its name derives. In the periodic table , potassium is one of the alkali metals , all of which have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge which combines with anions to form salts. In nature, potassium occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac - colored flame. It is found dissolved in seawater which is 0. Potassium is chemically very similar to sodium , the previous element in group 1 of the periodic table. They have a similar first ionization energy , which allows for each atom to give up its sole outer electron.
