+88 Measurements in Sci. Not.
Express each of the following measurements in scientific notation.
Speed of light in a vacuum, 299 792 458 m/s
Number of seconds in a day, 86 400 s
Mean radius of Earth, 6378 km
Density of oxygen gas at 0ºC and pressure of 101 kPa, 0.001 42 g/mL
Radius of an argon atom, 0.000 000 000 098 m
?
Speed of light in a vacuum, 299 792 458 m/s
Take this first question: start counting from the RIGHT until you get to the last digit, which is a 2. Don't include the last digit(2) in your counting. If you did that, you should get 8 numbers. This 8 will be the "exponent" of 10 as follows:299 792 458 =2.99792458 x 10^8. Or you could abbreviate it like this:
3.00 x 10^8. This is called scientific notation. Try the others and see how you do.
