(a)
Interpretation:
An approximate answer for the given calculation is to be stated. The ballpark answer is to be verified.
Concept introduction:
With experience, the answer to the chemical calculations can be estimated before using a calculator. After setting up the numerical calculation, each value is rounded off to one significant digit and the calculation is performed mentally. The resulting estimated answer is termed as ballpark answer as the value is only approximate.
