Test 1: Math & Chemistry Flashcards
Qualitative
quality-based, such as color, physical state
Quantitative
measurement of an amount or quantity
scientific notation is the method scientists use to
handle large and small numbers
Scientific notation is done by splitting up the number into what two parts?
the numerical value, and the factor of 10 by which it is multiplied (1000 is 1x10^3)
The power listed in scientific notation is done by counting the number of __ following the initial #
zeroes
If the power listed in scientific notation is negative, it describes
the total number of digits that come after the decimal. (.001 is 1x10^-3)
Prefix for billion
giga- (G), 10^9
Prefix for million
10^6, mega- (M)
Prefix for thousand
10^3, kilo (k)
Prefix for trillionth
10^-12, pico(p)
Prefix for hundredth
10^-2, centi- (c)
Prefix for thousandth
10^-3, milli- (m)
Prefix millionth
10^-6, micro- (u/m)
Prefix for billionth
10^-9, nano- (n)
What are the two parts of all quantitative measurements?
number and unit
The units of mass are
gram, pound, ounce, atomic mass unit (amu)
The units of length are
meter(m), inch, foot, yard(yd), mile(mi)
The units of time are
second(s)
The units of temperature are
kelvin(K), Celsius (degreeC), fahrenheit (degreeF)
Volume is found by
width x depth x height
Density =
Density = Mass/Volume
For solid objects that are not perfect cubes, measurement of volume can be done by
measuring the difference in volume when the solid object is added to a fixed amount of water
Prefix for trillion
Tera- (T), 10^12
Prefix for unit
1x10^0
