例如：molar mass of CO2 = 44 g/mol； molar mass of NaCl = 58.5 g/mol 简单来说，只有 molar mass 的 unit 是 g/mol，而其他都是没有 unit 的 relative mass。以 H2SO4 为例（Pure H2SO4 is molecular）： Relative atomic mass of H = 1 Relative atomic mass of S = 32 Rela...
The formula of Sodium chloride is NaCl . The atomic mass of sodium is 22.99gmol , and the atomic mass of chlorine is 35.45gmol . Thus, the formula mass of Sodium chloride is 22.99+35.45=58.44gmol. What is the difference between relative atomic mass and relative isotopic mass? The Relativ...
The invention relates to a formula of a soak solution for improving hardness of bristle. The formula comprises sodium chloride solutions, diethyl ether, vegetable oil, orange juice and egg white, and the mass percentages of all the components are as follows: 30% to 40% of the sodium chloride...
As an example, consider sodium chloride, NaCl, the chemical name for common table salt. Sodium chloride is an ionic compound composed of sodium cations, Na+, and chloride anions, Cl–, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu (see Figure 3)....

sodium atom (since it is missing an electron), this difference will be offset by the fact that a chloride anion is slightly more massive than a chlorine atom (due to the extra electron). Moreover, the mass of an electron is negligibly small with respect to the mass of a typical atom...
IUPAC Name: sodium chloride Other Names: table salt, halite, sodium chloric Chemical Formula: NaCl Molar Mass: 58.44 grams per mole Appearance: Pure sodium chloride forms odorless, colorless crystals. Many small crystals together reflect light back, making the salt appear white. The crystals may ...
