Answer to Question #108915 in General Chemistry for Bsvs

Question

Determine the number of particles in 10.0g of iron

Answer 1

Solution:

N_Fe=N_a*n_Fe -the number of particles of iron, here N_a=6.02*10²³mol^-1 - Avogadro constant.

n_Fe=m_Fe/A_Fe=10.0g / 56g*mol^-1=0.18mol - the iron amount of substance,

N_Fe=6.02*10²³mol^-1*0.18mol=1.08*10²³

Answer:

The number of particles in 10.0g of iron is 1.08*10²³
