How many moles are in 1.50 x 10 23?
There are 2.49 moles in 1.50 x 10^23 entities. This is calculated by dividing the number of entities by Avogadro's number, which is 6.022 x 10^23 entities/mol.
What are two forms of the conversion factor that will convert one mole to number of objects and number of objects to one mole?
To convert from moles to number of objects, the conversion factor is Avogadro's number (6.022 x 10^23 objects per mole). To convert from number of objects to moles, the conversion factor is the reciprocal of Avogadro's number (1 mole per 6.022 x 10^23 objects).

How many moles are in 3.612 x 10 to the 23 power?
1.00 mole is always 6.022*10+23 particles (of any kind)So divide 3.70*10+23 (electrons) by this number 6.022*10+23 (electrons/mole of electrons) and you'll get the number of moles of electrons.It is 3.70 / 6.022 = 0.614 mole of electrons
