![]() The mass number is nothing but the sum of the number of protons and number of neutrons present in the nucleus of the atom. Molecular weight is also called mass number. ![]() Therefore, the answer is – option (c) – Gram molecular mass of carbon is 12g It has an atomic mass of 12 atomic mass units or 12g. If we look at some periodic tables, we will actually find that the atomic mass of carbon is given as 12.011 u. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. It is a p-block element, present in Group 14 and 2nd period. The atomic mass for a carbon-12 atom is 12 u. Element Carbon (C), Group 14, Atomic Number 6, p-block, Mass 12.011. \Ĭarbon is an element with atomic number 6. Molar mass of an element and atomic mass of an element have the same value. It is due to the fact that the atoms of different elements contain different numbers of protons, neutrons, and electrons, and therefore they have different masses. All elements have different molar masses. Converting the mass, in grams, of a substance to moles requires a conversion factor of (one mole of substance/molar mass of. If the mass of a substance is known, the number of moles in the substance can be calculated. The molar mass is an average of many instances of the compound, which often vary in mass due to. 1 The molar mass is a bulk, not molecular, property of a substance. The periodic table lists the atomic mass of carbon as 12. The molar mass of an element is found on the periodic table, and it is the element's atomic weight in grams/mole (g/mol). In chemistry, the molar mass ( M) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of said compound. It should be noted that each element has its own unique molar mass. The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole. “The mass in grams of one mole of substance is called molar mass”. Refer to the periodic table to solve this question. Atomic number refers to the number of electrons present in the element. Hint: Do not confuse atomic mass with atomic number.
