The atomic mass of Li is 9 and K is 39. Convert grams K to moles  or  moles K to grams. The atomic number tells you how many protons you have in the nucleus. From the periodic table you can see that carbon has a atomic number 6, which is its proton number. ›› K molecular weight. To complete this calculation, you have to know what substance you are trying to convert. of a chemical compound, More information on The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. We use the most common isotopes. Example: convert 15 u to kg: 15 u = 15 × 1.6605402E-27 kg = 2.4908103E-26 kg The mass of K is provided, and the corresponding amount of K in moles is requested. CR58 common chemical compounds. These relative weights computed from the chemical equation are sometimes called equation weights. Find My Location: IP address, city, latitude & longitude. Name: Potassium. The atomic mass of K is the number of protons and neutrons in the atom's nucleus. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. K: Atomic Number: 19: Atomic Mass: 39.0983 atomic mass units: Number of Protons: 19: Number of Neutrons: 20: Number of Electrons: 19: Melting Point: 63.65° C ... and the Arabic word qali, meaning alkali. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. The decay of 40 K to 40 Ar is used in potassium-argon dating of rocks. This is a list of chemical elements, sorted by atomic mass (or most stable isotope) and color coded according to type of element.Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Minerals are dated by measurement of the concentration of potassium and the amount of radiogenic 40 Ar that has accumulated. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … Price of commodities: gold, silver, oil, live cattles and more. Justin XoXo :), The kilogram (SI unit symbol: kg) is the base unit of mass in the Metric system and is defined as being equal to the mass of the International Prototype of the Kilogram ..more definition+. THe atomic number of K will be above the symbol. Convert grams K to moles or moles K to grams ›› Percent composition by element Symbol: K. Atomic Number: 19. Molar mass of K = 39.0983 g/mol. The symbol K comes from the Latin word kalium, meaning alkali. Molar mass of K is 39.09830 ± 0.00010 g/mol Compound name is potassium Convert between K weight and moles The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Browse the list of Melting Point: 63.65 °C (336.8 K, 146.57 °F) Boiling Point: 774.0 °C (1047.15 K, 1425.2 °F) Number of Protons/Electrons: 19. Users experience is very important, that's why I use non-intrusive ads. A common request on this site is to convert grams to moles. Referring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. This site is my passion, and I regularly adding new tools/apps.

In a human body of 70 kg mass, about 4,400 nuclei of 40 K decay per second. Classification: Alkali Metal. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. The atomic number is the number of protons in an atom. assuming that your number of protons and electrons is the same, the number of electrons is the same number as the atomic number. The atomic … The atomic weights used on this site come from NIST, the National Institute of Standards and Technology.
