Heat capacity is the ability of a material to store heat, higher the heat capacity higher the amount to heat stored by the material. Heat transfer usually varies inversely with heat capacity, i.e heat transfer will decrease with increase in heat capacity and vice versa. Thermal diffusivity is the ratio of thermal conductivity to the heat capacity, it says how fast (or slow) heat is transferred inside a material. Usually thermal diffusivity is directly proportional to the heat transfer rate, since heat capacity appears on the denominator, heat transfer is inversely proportional to the heat capacity.
Answer:
69.726 amu
Explanation:
From the question given above, the following data were obtained:
Isotope A:
Mass of A = 68.926 amu
Abundance of A (A%) = 60.00%
Isotope B:
Mass of B = 70.925 amu
Abundance of B (B%) = 40.00%
Average atomic mass =?
The average atomic mass of the element can be obtained as shown below:
Average atomic mass
= [(Mass of A × A%)/100] + [(Mass of B × B%)/100]
= [(68.926 × 60)/100] + [(70.925 × 40)/100]
= 41.3556 + 28.37
= 69.726 amu
Therefore, the average atomic mass of the element is 69.726 amu
