To find: The atomic mass of $24Mg$ .

Expert Solution & Answer

Answer to Problem 2.39QP

Solution

The atomic mass of $24Mg$ $= 23.98 amu$

Explanation of Solution

The atomic mass of $24Mg$ is given below,

$Average atomic mass= ∑(Mass of isotope × Percent abundance)$

Multiplying the mass of an isotope by its fractional abundance will give the contribution to the average atomic mass of that particular isotope.

The atomic masses of $25Mg = 24.9858 amu = 10%$

The atomic masses of $26Mg = 25.9825 amu = 11.01%$

The atomic masses of $24Mg = 78.99%$

The atomic mass of $24Mg$ , x, given the contribution to the average atomic mass of $25Mg$ and $26Mg$ , and the average atomic mass of magnesium.

$The fractional abundance of 25Mg = 10% =10.0100 = 0.1$

$The fractional abundance of 26Mg = 11.01% =11.01100 = 0.1101$

$Atomic mass calculation is given below,(0.1000)(24.9858 amu 25Mg)+(0.1101)(25.9825 amu 26Mg)+(0.7899)(x amu24Mg) = 24.3050 2.4985 + 2.8606 + 0.7899 (x) = 24.3050 0.7899 (x) = 24.3050 - 5.3591 0.7899 (x) = 18.9459 (x) = 18.94590.7899 (x) = 23.98 amu$
