When it comes to a covalent molecular compound, the molar mass is the mass of 1 mol of molecules of that compound, while for an ionic compound, the molar mass is the mass of 1 mole of formula units. Thus, the molar mass of a substance is the mass (grams per mole) of 6.022 × 1023 atoms (Avogadro number), molecules, or units of that substance. However, if we consider a weight of substance that is the same as its formula (molecular) weight expressed in grams, we have only one number to know: Avogadro's number. Avogadro's number. Avogadro's number is known to ten significant digits: NA = 6.022141527 ×1023. (4.2.1) (4.2.1) N A = 6.022141527 × 10 23. However, you only need to know it The unit to measure the mass of the compound is gram. The unit to measure the molar mass of the compound is grams per mole or g/mol. g / m o l. The molar mass is defined as the mass of 1mol, 1 m o l, which is in the SI measured in g/mol. g / m o l. Example: The molar mass of water H2O: MM = 18.016g/mol H 2 O: M M = 18.016 g / m o l . The answers are 5C, 1N, and 5H. The empirical formula is C 5 H 5 N, which has a molar mass of 79.10 g/mol. To find the actual molecular formula, divide 240, the molar mass of the compound, by 79.10 to obtain 3. So the formula is three times the empirical formula, or C 15 H 15 N 3. The mass of one molecule is defined as the molecular mass of a compound. Molar mass is the mass of a substance in a particular quantity. Compounds, atoms, or molecules are measured in molar mass. Molecular mass is measured specifically for molecules. g/mol is the SI unit for molar mass. Numerically, the molar mass is equal to the atomic mass of a given atom or a molecule, so we can look up the molar mass of an element in the periodic table. For example, we can say that the mass of Cu is 63.55 amu or 63.55 g/mol. The molecular mass of water is 18.0 amu, and the molar mass is 18.0 g/mol. Molar mass is the mass in grams of one mole of a substance. Its numerical value is equal to the formula mass that is expressed in a.m.u. For example, glucose has a formula mass of 180.0 a.m.u. So, the molar mass (mass in gram of one mole) of glucose is 180.0 g/mol. There must be confusion here about molar mass being the same as molecular mass. m(X12X2122C) =12 amu = 12 g/mol m ( X 12 X 2 2 12 C) = 12 a m u = 12 g / m o l. So finally we get that 1 g/mol =1 amu 1 g / m o l = 1 a m u . However, my chemistry teacher is telling me that those are two completely different things and that I am confused between the mass per atom and the mass per 6.022 ⋅1023 6.022 ⋅ 10 23 atoms.

is molecular mass and molar mass the same
