(a)
Interpretation:
To express the significant figure for the given quantity 4.5609 g salt.
Concept introduction:
The significant figures are also known as the significant digits. It is the uncertainty associate with the measurement by rounding the results. Moreover the significant figures are defined in a number of the digits with certainty and first uncertain digit. The measurement is a characteristic number to the object or event that can be compared with other object. The scope of the measurement depends upon the context and event. Measurement is commonly used as the international system of unit as a comparison framework. The system defines seven fundamental units like kilogram, meter, candela, ampere, kelvin and mole. The metric system is a decimal system of the measurement based on the units for the length, meter, the mass, the kilogram. It exists in the several forms with different choices of the basic units. The metric system indicates the single basic unit for the number of physical quantities. Other quantities are derived from the SI units.

Answer to Problem 56E
The significant figure for 4.5609 g salt is 5.
Explanation of Solution
To identifying the significant figures;
Number system having all non-zero digits is significant i.e., 1, 2, 3…
Zero between the numbers having non-zero are said to be significant: 102, 2005…
Leading zeros are never significant figures: 0.02, 001.887…
In a number system with a decimal point that is trailing zeros are significant figures: 2.02000, 5.4000….
In a number system without a decimal point that is trailing number zero may or may not said to be a significant figure.
So for the given question 4.5609 g salt, all is non-zero digit with the significant figure is 5.
