Answer:
The percentage error is -2.4 %
Explanation:
The percentage error is calculated by the following formula;
[tex]Percentage \ error = \dfrac{Approximate - Exact }{Exact}[/tex]
The given parameters are;
The atomic mass of cobalt = 58.933 amu. = The exact value
The mass of cobalt as measured by the scientist = 57.514 = The approximate value
Therefore, the percentage error is given plugging in the values into the above equation for percentage error as follows;
[tex]Percentage \ error = \dfrac{(57.514- 58.933 )}{58.933 } \times 100 = -2.41\%[/tex]
The percentage error = -2.4 %.
