the average atomic mass of Kl = 312.2 a.m.u

Explanation:

To calculate the average atomic mass of the element you need to know the mass mass of the isotope and the abundance.

In our case we calculate the abundance of each isotope as following:

abundance of a particular isotope = number of gas atoms of the particular isotope / total number of gas atoms

abundance of ³¹⁰Kl = 10 / 50 = 0.2

abundance of ³¹²Kl = 10 / 50 = 0.2

abundance of ³¹³Kl = 30 / 50 = 0.6

Now to calculate the average atomic mass of Kl we use the following formula:

the average atomic mass = mass of isotope 1 × abundance of isotope 1 + mass of isotope 2 × abundance of isotope 2 +...+ mass of isotope n × abundance of isotope n

the average atomic mass of Kl = 310 × 0.2 + 312 × 0.2 + 313 × 0.6

the average atomic mass of Kl = 312.2 a.m.u
