Problem 7PE

Determining the Number of Significant Figures in a Calculated QuantityThe width, length, and height of a small box are 15.5, 27.3, and 5.4 cm, respectively. Calculate the volume of the box, using the correct number of significant figures in your answer.It takes 10.5 s for a sprinter to run 100.00 m. Calculate her average speed in meters per second and express the result to the correct number of significant figures.

Step-by-Step Solution:
Step 1 of 3

CHAPTER ONE: ATOMS MATTER  Matter – anything that takes up space and has mass  Composed of particles  Structure determines the properties  Atoms are the building blocks of matter  2+ atoms = molecule  Early ideas of matter - Leucippus and Democritus – first to propose the definition of matter - John Dalton – evidence supported Leucippus and Democritus States of Matter  Solid - Atoms/molecules pack closely together - Vibrate but don’t move past each other - Fixed volume/shape  Liquid - Atoms/molecules pack close but able to move past each other - Fixed volume but no fixed shape - Assume shape of container  Gas - A lot of space between atoms/molecule
