How many atoms are there in 24 moles of Fe?

There are atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

Thus, we can conclude that there are atoms in 24 moles of Fe.

chemistry sucks a**

explanation:

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
