How many atoms are present in 14 g of iron

1.51 × 10²³ atoms

Explanation:

First, we convert 14g of iron (Fe) to moles using the formula below:

mole = mass ÷ molar mass

Molar mass of Fe = 55.85g/mol

mole = 14g ÷ 55.85g/mol

mole = 0.251mol

The number of atoms in 0.251 mol of Fe is calculated as follows:

number of atoms = n × nA

Where;

n = number of moles

nA = Avagadros number (6.02 × 10²³)

number of atoms = 0.251 × 6.02 × 10²³

number of atoms = 1.51 × 10²³ atoms.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
