Answer:
2.26 × 10²⁴ atoms of Fe
Explanation:
To calculate the amount of atoms of a substance using the amount of moles, we must multiply by Avagadro's number.
(3.75mol) × (6.02 × 10²³) = 2.26 × 10²⁴ atoms of Fe
NaCl would form because it’s a single replacement reaction
Mr: 207.2
m=n×Mr= 6.53×207.2= 1353.02g
Wavelength relates to frequency as follows: λ=vf in which f is the frequency, v is the speed of light, and λ is the wavelength.
