• EXAMPLE 0.000 02 = 2 x 10-5 0.000 02 ≠ 00002 x 10-5 4) Captive zeros (zeros between non-zero numbers) should be written in scientific notation. EXAMPLE 904,000 = 9.04 x 105 904,000 ≠ 9.4 x 105 PRACTICE 1.1 Convert the following numbers to scientific notation.
• Significant figures are used. Results are shown only with as many significant figures as the quantity that was entered. Scientific notation may be used for large results or if the number of significant digits would be ambiguous otherwise. The calculator follows proper rounding rules for scientific purposes.
• Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work? We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term). Here are some examples of scientific ...

Do not use scientific notation (exponents) or fractions in your answers to the questions below. Write all of the zeros. Length Measurement of Length. Measure the width of this page using a small plastic ruler. Record your measurement in 1) millimeters, 2) centimeters, and 3) meters. Record your answers on the answer sheet.
470,000 has two significant figures 400 or 4x10 2 indicates only one significant figure. (To indicate that the trailing zeros are significant a decimal point must be added. 400. has three significant digits and is written as 4.00x10 2 in scientific notation.
Convert the following numbers to scientific notation: a. 1,234 b. 0.893 c. 1.78 d. 9283.54 Answers: a. 1.234 x 10 3 b. 8.93 x 10-1 c. 1.78 x 10 0 (already between 1-10!) d. 9.28354 x 10 3 Make the following calculations to the correct number of significant figures: a. (6.2 x 106)/(3.1 x 103)= b. (3.66 x 10-5)/(2.0 x 10-3)= c. ((8.2 x 106)(5.0 x ... III. Converting between millimeters of mercury and kilopascals. 760.0 mmHg equals 101.325 kPa, so both values will be involved. This situation is slighly unusual because most conversions involve a one, usually in the denominator. The conversion examples above are examples of a one being involved. For example, 760.0 mmHg / 1 atm in examples 1 and 2.
numbers. This method is called scientific notation. Scientific Notation is based on powers of the base number 10. Distance from Earth to the Sun: 149 600 000 km = 1.496 × 108 km Charge of one electron: -0.000 000 000 000 000 000 1602 = -1.602 × 10-19 Coulombs A positive exponent shows that the decimal point is shifted that number of places to ...
Scientific notation Scientific method Hypothesis Potential energy Specific heat capacity Heat Scientific law System Temperature Polymer _____ is dependent upon the motion of an object in relation to another object. The measure of the average kinetic energy of a samples particles is a measure of its _____. gold is 0.000 000 000 000 000 000 000 327 gram. Writing and using such large and small numbers is very cumbersome. You can work more easilv with these numbers by writing them in scientific, or exponential, notationa In scientific notation, a given number is written as the product of two numbers: a coefficient and 10 raised to a power.
Milligrams. The milligram is the mass equal to 1/1,000 of a gram, or 0.0154 grains.. The milligram, or milligramme, is an SI unit of weight in the metric system. In the metric system, "milli" is the prefix for 10-3. Be familiar with the units of the metric system of measurement. Be able to convert measurements, especially within the metric system, by using dimensional analysis. Determine the number of significant figures in a measurement. Distinguish between physical and chemical properties and changes.
