Write each of the following in terms of the SI base unit (that is, express the prefix as the power of 10).
- a 6.6 mK
- b 275 pm
- c 22.1 ms
- d 45 μm
(a)
Interpretation:
The given terms of SI base unit and prefix has to be expressed as power of 10.
Concept Introduction:
Metric prefix is the one which follows a basic unit of measurement in order to indicate fraction or multiple of the units. There are seven SI base units. From these base units all the other units can be derived. Prefix is used to indicate the value in power of 10. This is a physical quantity and it is known as SI prefix. The seven base units are meter, kilogram, second, kelvin, mole, ampere, and candela. Some of the prefix are mega, kilo, deci, centi etc.

- Although the preferred SI unit of area is the square meter, land is often measured in the metric system in hectares (ha). One hectare is equal to 10,000 m2. In the English system, land is often measured in acres (1 acre = 160 rod2). Use the exact conversions and those given in Exercise 47 to calculate the following. a. 1 ha = __________ km2 b. The area of a 5.5-acre plot of land in hectares, square meters, and square kilometers c. A lot with dimensions 120 ft by 75 ft is to be sold for 6500. What is the price per acre? What is the price per hectare?arrow_forwardAll of the following processes involve a separation of either a mixture into substances or a compound into elements. For each, decide whether a physical process or a chemical reaction is required. a Sodium metal is obtained from the substance sodium chloride. b Iron filings are separated from sand by using a magnet. c Sugar crystals are separated from a sugar syrup by evaporation of water. d Fine crystals of silver chloride are separated from a suspension of the crystals in water. e Copper is produced when zinc metal is placed in a solution of copper(II) sulfate, a compound.arrow_forwardThe following pairs of substances represent heterogeneous mixtures.
