4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of NaClS2: 22.98976928 g/mol + 35.453 g/mol + 64.13 g/mol = 122.57276928 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in NaClS2, divide ea...
Finally, add together the total mass of each element to get the molar mass of Al(NaCl): 26.9815386 g/mol + 22.98976928 g/mol + 35.453 g/mol = 85.42430788 g/mol 5. Find Mole Fraction To find the mole fraction and percentage of each element in Al(NaCl), divide each total from step ...
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...
Molar Mass & Molarity Molar Mass • Mass in grams of one mole of an element or compound. • Numerically equal to the atomic weight of the element or the sum of all the atomic weights in the formula. • Round all atomic masses to keep 2 decimals. Molar Mass Examples • NaCl =...

For example, common table salt or sodium chloride (NaCl) 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 by adding the average atomic masses of its constituent elements: When computin...
To find the mass of a compound, you must add up the individual masses of its component elements. For example, table salt (NaCl) has two elements. The molar mass of sodium is 23g/mol. The molar mass of chlorine is 35.5g/mol. So when you add those together, you get the molar mass ...
The molar mass of atoms of an element is given by the atomic mass of the element [2]multiplied by the molar mass constant, M u = 1×10−3 kg/mol = 1 g/mol:[3]M (H) = 1.007 97(7) × 1 g/mol = 1.007 97(7) g/mol M (S) = 32.065(5) × 1 g/mol = 32.065...
