Answer:
58.702
Step-by-step explanation:
Data obtained from the question include:
Mass number of isotope 1 (M1) = 57.93
Abundance of isotope 1 (M1%) = 67.76%
Mass number of isotope 2 (M2) = 59.93
Abundance of isotope 2 (M2%) = 26.16%
Mass number of isotope 3 (M3) = 60.93
Abundance of isotope 3 (M3%) = 1.25%
Mass number of isotope 4 (M4) = 61.93
Abundance of isotope 4 (M4%) = 3.66%
Mass number of isotope 5 (M5) = 63.93
Abundance of isotope 5 (M5%) = 1.16%
Relative atomic mass =...?
The relative atomic mass(RAM) of the element can be obtained by doing the following:
RAM = [(M1×M1%) /100] +[(M2×M2%) /100] + [(M3×M3%) /100] + [(M4×M4%) /100] + [(M5×M5%) /100]
RAM = [(57.93×67.76)/100] + [(59.93×26.16)/100] + [(60.93×1.25) /100] + [(61.93×3.66)/100] + [(63.93×1.16)/100]
RAM = 39.253 + 15.678 + 0.762 + 2.267 + 0.742
RAM = 58.702
Therefore, the relative atomic mass (RAM) of the element is 58.702
