(a)
Interpretation:
The formula mass of the given compound
Concept Introduction:
Significant Figures:
While reporting a reading of a measurement, the digits that are considered to be significant irrespective of the place of location of decimal point are called significant figures.
All the digits in a measurement except zero are considered significant, whereas zero is considered as significant only when it lies in the middle of the digit or at the end of number on the right-hand side of a decimal point.
To write: The formula mass of the given compound with a reasonable number of digits
