To find the number of moles contained in 4.131 x 10^24 particles, we need to use Avogadro's number. Avogadro's number, denoted by N, is the number of atoms, molecules, or other entities in one mole of a substance. It is approximately equal to 6.022 x 10^23.
So, we can use this formula to find the number of moles:
moles = (number of particles) / N
Where N = 6.022 x 10^23
Substituting the given value of particles:
moles = (4.131 x 10^24 particles) / (6.022 x 10^23)
moles = (4.131 x 10^24) / (6.022 x 10^23)
moles = 0.6869
So, 4.131 x 10^24 particles contains approximately 0.6869 moles.
