Define the answer
a. Atomic mass
b. Relative atomic mass
c. Gram molecular mass
d. Mole
Answers
Explanation:
(a) atomic mass
The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
(b) relative atomic mass
Relative atomic mass (symbol: Ar) or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant
(c) gram molecular mass.
Gram molecular mass is the mass in grams of one mole of a molecular substance. Gram molecular mass is the same as molar mass. The only difference is that gram molecular mass specifies the mass unit to be used. Gram molecular mass may be reported in grams or grams per mole (g/mol).
(d) Mole
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance
a. Atomic mass - The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
b. Relative atomic mass - The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine.
c. Gram molecular mass - Gram molecular mass is the mass in grams of one mole of a molecular substance. Gram molecular mass is the same as molar mass. ... Gram molecular mass may be reported in grams or grams per mole (g/mol).
d. Mole - A mole of a substance is that containing 6.022 * 10^23 molecules of that substance. A mole of substance contains Avogadro's number number of molecules in it.
