ASVAB General Science - Exam Topics Sample Questions

How many orders of magnitude difference are there between 1X10-3 M to 1X10-9 M?

Correct Answer:
six (6).


the concept of "orders of magnitude" is used in science to describe the comparative scale or size of numbers, where each order of magnitude represents a tenfold difference. an order of magnitude difference means that one number is 10 times larger or smaller than another. for example, 100 is an order of magnitude greater than 10 because 100 is 10 times 10.

in the case of comparing two concentrations given in scientific notation, such as 1x10^-3 m and 1x10^-9 m, the orders of magnitude difference between them can be determined by evaluating the exponents of the 10s in their expressions. the given concentrations are 1x10^-3 m, representing a thousandth (0.001) molarity, and 1x10^-9 m, representing a billionth (0.000000001) molarity.

to find the number of orders of magnitude between these two concentrations, subtract the exponent of the smaller concentration from the exponent of the larger concentration. here, the exponents are -3 and -9 respectively. therefore, the absolute difference in exponents is |-3 - (-9)| = |-3 + 9| = 6. hence, there are six orders of magnitude difference between 1x10^-3 m and 1x10^-9 m.

this method of calculating orders of magnitude by examining the exponents in scientific notation allows quick and intuitive comparisons of scale and proportion in various scientific contexts, ensuring clarity and precision in understanding the relative magnitudes of different values. the correct answer to the question is "six (6)."
