Respuesta :
Density = 0.8104 g/ml
⇒ mass/volume = 0.8104 g in 1ml volume.
Number of moles = Mass (g) / Molar mass (g/mol)
⇒ No. of moles =0.8104/88.148 = 9.1936 x 10^-3 mole in 1 ml volume
So, in 2.66 ml of isopentyl alcohol,
No. of moles = 2.66 x 9.1936 x 10^-3 = 24.454976 x 10^-3 mole
What is the Mole concept?
- The mole idea is a useful way to indicate how much of a substance there is. Any measurement can be divided into two components: the magnitude in numbers and the units in which the magnitude is expressed.
- The particles that are often counted are chemically identical but individually separate entities. The constituent particles of a solid, however, remain stable and bound in a lattice structure, albeit they may be separated without losing their chemical identity.
- The mole is nevertheless used to describe the number of atoms linked together rather than a count of molecules in other instances, such as diamond, where the entire crystal is effectively one single molecule.
