The mole is an important concept for talking about a very large number of things — 6.02 x 1023 of them to be exact. This module shows how the mole, known as Avogadro’s number, is key to calculating quantities of atoms and molecules. It descr
The term mole is derived from a Latin word that means pile or heap. The mole of any substance represents \(6.022 \times {10^{23}}\) particles of that substance. Let us learn about molecular mass and mole concepts in detail. Scroll down to learn more!
H (Hydrogen) 10 × 1.00794 = 10.0794 O (Oxygen) 3× 15.9994 = 47.9982 4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of C11H10O3: 132.1177 g/mol + 10.0794 g/mol + 47.9982 g/mol = 190.1953 g/mol 5. Find Mole Fraction To...
1 mole of any element contains the same number of atoms as 1 mole of any other element. The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. Themolar massof an element (or compound) is the mass in gr...
