Amount (mol) of Mn atoms in 62.0 mg of Mn 1.12 moles.
The mole is the smallest unit of the atom which use to represent how many atoms moles or molecules are used in a chemical process or in a chemical reaction which is always equal to 2.303 ×10²³ moles for one atom.
To calculate the mass of the number of H⁻ ions in 5.82 g of SrH₂ the formula will use is,
number of moles = mass / molar mass
molar mass of Mn = 54.93
mass of Mn atoms = 62.0 mg
substituting the value in the equation,
number of moles = 62.0 mg / 54.93
a number of moles = 1.12 moles
Therefore, in 1.12 moles, the Amount (mol) of Mn atoms in 62.0 mg of Mn
