Whenever two measurement are equal, or equivalent, a ratio of these two measurements will equal ___1____. A ratio of equivalent measurement is called a ___2___. When a measurement is multiplied by a conversion factor, the value of the measurement ___3____. In ____4___, the units that are a part of the measuerements are used to help solve the problem. The form of the conversion factor that is used is the one in which the unit of the ___5____ is the denominator.
I think 1, 2, 3, and 4, are ok.
For 5, let's look at a conversion.
12 inches = 1 foot
conversion factor = 12 in/1 ft
OR 1 ft/12 inches.
given: 3 ft.
convert to inches.
3 ft x (12 inches/1 ft) = 36 inches.
So the denominator is the part of the conversion factor that must cancel and that is the "given" or "the beginning unit" or some word like that. You probably had that in class or its in your notes. Note that we started with ft and we want to cancel the ft so ft must be on the bottom.
classify each of these statements as always true, sometimes true, or never true. __ST___11)The unit of a conversion factor must cancel. __AT___12)the conversion factor for changing grams and milligrams is 1g/1000mg
please explain the dimensional analysis, and atomic structure? The conversion table for metric to English and English to metric? Dimensional analysis is the procedure for changing from one unit to another. For example, convert 12
Completion Mole ratios from balanced equations may be used to solve problems with other units such as numbers of ______ and _______ of gases at STP. The _______ from the balanced equation are used to write conversion factors
Are most factors unity? Is this True or false I'm thinkin true.. The actual size of a measurement multiplied by a conversion factor remains the same, beacause the measurement being converted is multiplied by unity. okay
