(a)
Interpretation:
To state the number of significant figures in the following quantity 52.0 cm3
Concept introduction:
The measurement is a characteristic number to the object that can be compared with other objects. 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 has 7 fundamental units like kilogram, meter, candela, ampere, kelvin and mole. The metric system is a decimal system used to measure the length, meter, the mass, the kilogram. The metric system is a single basic unit used for number of physical quantities. The quantities are derived from the SI units. For this scientific notation is most important.
Scientific notation is the way to express the numbers that are too big or small that can be written conveniently in the decimal form. It is commonly used by the scientist, mathematics, to simplify the certain arithmetic operation. In the scientific notation, the numbers are indicated by
M
Where the n is the integer and m is the real number.
(b)
Interpretation:
To state the number of significant figures in the following quantity 0.00020 kL.

Concept introduction:
The measurement is a characteristic number to the object 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 has 7 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 several forms with various choices of the basic units. The metric system indicates a single basic unit for number of physical quantities. Other quantities are derived from the SI units.
Mass, is a dimensional quantity represents the amount of the matter in a particle. The kilogram comes under the category of the mass. The kilogram is the basic unit of mass in the international unit system. The gram or 1/1000 kilogram was first defined in the year 1795 as mass of 1 cubic centimeter of water with referred to the melting point of the ice. The mega-gram or often it is called as ton.

(Note: it's not equal to the difference in chemical shifts.) Round your answer to 2 significant digits, and be sure it has an appropriate unit symbol. = O O a will shift left, c will shift right. O a will shift right, c will shift left. a and c will both shift left, with more space between them. Suppose a new spectrum is taken with a 500 MHz spectrometer. What will be true about this new spectrum? O a and c will both shift left, with less space between them. O a and c will both shift right, with more space between them.
