- 2.1: Taking Measurements
- Chemists measure the properties of matter and express these measurements as quantities. A quantity is an amount of something and consists of a number and a unit. The number tells us how many (or how much), and the unit tells us what the scale of measurement is. For example, when a distance is reported as '5 kilometers,' we know that the quantity has been expressed in units of kilometers and that the number of kilometers is 5.
- 2.2: Scientific Notation - Writing Large and Small Numbers
- Chemists often work with numbers that are exceedingly large or small. For example, entering the mass in grams of a hydrogen atom into a calculator requires a display with at least 24 decimal places. A system called scientific notation avoids much of the tedium and awkwardness of manipulating numbers with large or small magnitudes.
- 2.3: Significant Figures - Writing Numbers to Reflect Precision
- Uncertainty exists in all measurements. The degree of uncertainty is affected in part by the quality of the measuring tool. Significant figures give an indication of the certainty of a measurement. Rules allow decisions to be made about how many digits to use in any given situation.
- 2.4: Significant Figures in Calculations
- To round a number, first decide how many significant figures the number should have. Once you know that, round to that many digits, starting from the left. If the number immediately to the right of the last significant digit is less than 5, it is dropped and the value of the last significant digit remains the same. If the number immediately to the right of the last significant digit is greater than or equal to 5, the last significant digit is increased by 1.
- 2.5: The Basic Units of Measurement
- Metric prefixes derive from Latin or Greek terms. The prefixes are used to make the units manageable. The SI system is based on multiples of ten. There are seven basic units in the SI system. Five of these units are commonly used in chemistry.
- 2.6: Problem Solving and Unit Conversions
- During your studies of chemistry (and physics also), you will note that mathematical equations are used in a number of different applications. Many of these equations have a number of different variables with which you will need to work. You should also note that these equations will often require you to use measurements with their units. Algebra skills become very important here!
- 2.7: Solving Multistep Conversion Problems
- Sometimes you will have to perform more than one conversion to obtain the desired unit.
- 2.8: Units Raised to a Power
- Conversion factors for area and volume can also be produced by the dimensional analysis method. Just remember that if a quantity is raised to a power of 10 both the number and the unit must be raised to the same power of 10.
- 2.9: Density
- Density is a physical property found by dividing the mass of an object by its volume. Regardless of the sample size, density is always constant.

Josie is a kindergarten teacher and wants to make felt toys for her students. These felt toys will be cylinders, meant to replicate cans. She wants to put the felt toys in the new play kitchen in her classroom. To find the amount of felt she needs, Josie will need to calculate the surface area of the cans she plans to make. This chapter will explain how to find surface area of different objects, including cylinders.
Learning Outcomes
By the end of this section, you will be able to:
- Find volume and surface area of rectangular solids
- Find volume and surface area of spheres
- Find volume and surface area of cylinders
- Find volume of cones
Before you get started in this module, try a few practice problems and review prior concepts.

In this section, we will finish our study of geometry applications. We find the volume and surface area of some three-dimensional figures. Since we will be solving applications, we will once again show our Problem-Solving Strategy for Geometry Applications.
Mount and blade warband marry claimant. Marrying claimant Playing Floris, trying to marry Lady Isolla of Suno, as I made her the ruler of Swadia. I have the more renown of our whole faction, 0 controversy, 12 right to rule (growing to the point she's already ♥♥♥♥♥♥ about it). The option for marrying the claimant will not show up unless the player has completed the quest and defeated the original faction. Good relations with ruler. High renown, honour and right to rule The ruler will refuse to marry the player if he/she does not have enough honor. Another new option in Mount & Blade: Warband is to woo a lady with poetry and marry her. You can do it in secret or you can get her father's permission (sometimes brother). It takes several visits to worm your way into a bedchamber and it's not a good idea to rush. You can learn poems in taverns and there seems to be a limit of five in total.
