Step-by-step explanation:

Number of moles equal to the given mass divided by molar mass of the element or compound.

Mathematically, No. of moles =
(mass given)/(Molar mass)

The given mass is
4.86 * 10^(4) g and molar mass is 24.30 g/mol.

Therefore, calculate the number of moles as follows.

No. of moles =
(mass given)/(Molar mass)

=
(4.86 * 10^(4) g)/(24.30 g/mol)

=
0.2 * 10^(4) mol

=
2 * 10^(3) mol

or, = 2000 mol

Thus, we can conclude that
4.86 * 10^(4) g of Mg has 2000 moles.

Answer : The moles of magnesium (Mg) is,
1.99* 10^3moles

Solution : Given,

Mass of magnesium (Mg) =
4.86* 10^4g

Molar mass of magnesium (Mg) = 24.31 g/mole

Formula used :


\text{Moles of Mg}=\frac{\text{Mass of Mg}}{\text{Molar mass of Mg}}=(4.86* 10^4g)/(24.31g/mole)=1.99* 10^3moles

Therefore, the moles of magnesium (Mg) is,
1.99* 10^3moles
