The density of aluminum is 2.7 g/cm3. What volume will 13.5 grams of aluminum occupy?
Density = Mass/Volume 2.7 g/cm3 = 13.5 grams/Volume Volume = 13.5 grams / 2.7 (g/cm3) Volume = 5 cm3

Box A and Box B both have the same volume but Box A has a greater density. Draw a picture to show this difference and explain your reasoning.
Box A should contain more matter than Box B. This is because density is a measure of mass divided by volume and the more mass something contains, the greater the density.

A student estimated a mass to be 325g, but upon carefully measuring it, found the actual mass to be 342g. What is the percent error?
| Experimental Value - Accepted Value | ---------------------------------------------- x 100 % Accepted Value | 325 g - 342 g| 17 ------------------ x 100 % = ------ x 100 % = 4.97 % Error 342 g 342

Describe what it means to go "up" the metric system and what by what factor of ten would you multiply by to convert from grams to kilograms.
Going "up" the ladder means that you are dividing by a factor of ten for each step that you go up. Because there are 3 steps between grams and kilograms, you would multiply by (1/1000).
