The label on a box of cereal gives the mass of cereal in two units: 978 grams and 34.5 oz. Use this information to find a conversion factor between the English and metric units. Answer. PROBLEM 1.7.1.4 1.7.1. 4. Soccer is played with a round ball having a circumference between 27 and 28 inches and a mass between 14 and 16 oz. 5. Calculate the number of seconds in a year. 6. A light year is the distance that light travels in one year. Determine the number of miles, meters, and kilometers in one light year. 7. A single layer of gold atoms forms a surface whose dimensions are 1.0 x 103 angstroms by 1.0 x 103 angstroms. 1 angstrom = 10-10 meter.

Intro to General Chemistry Dimensional Analysis Practice Problems 94 problems 1 PRACTICE PROBLEM The concentration of dissolved iron in the Pacific Ocean is 2.0 × 10 -9 g/mL. If the volume of the Pacific Ocean is estimated to be 7.14 × 10 20 L, calculate the mass (in g) of dissolved iron. 2 PRACTICE PROBLEM If another conversion is necessary, repeat Steps 1 and 2 until you arrive at the wanted unit. Here is an example of a conversion that requires two steps: Convert 3.00 feet to centimeters given 1 foot = 12 inches and 1 inch = 2.54 centimeters. 3.00 ft x 12 in./ft x 2.54 cm/in. = 91.4 cm.

Dimensional Analysis Worksheet Chemistry
Dimensional analysis is an essential problem-solving tool and students should be encouraged to practice the skill repeatedly. Some, but not all, of the AP connections are listed below. AP Chemistry: III. Reactions B. Stoichiometry 3. Mass and volume relations with emphasis on the mole concept, including empirical formulas and limiting reactants Dimensional Analysis Worksheet Directions: You must show all work and it must be presented in a neat and orderly fashion. The numbers in your setups and answers must include proper units and significant figures. You must use proper dimensional analysis technique, which means use one continuous conversion. Unit Conversion and Dimensional Analysis Frequently in Chemistry you will be provided with data describing a particular quantity in a certain unit of measurement, and you will be required to convert it to a different unit which measures the same quantity. This process is frequently described as Unit Conversion.

Honors Chemistry Dimensional Analysis You must show dimensional analysis set up to receive credit on this worksheet. Conversion Factors (you will need a couple of commonly known ones too) 1 in = 2.54 cm 1 lb = 4.45 N 2 1 mile = 1.6 km 6.5 cm2 = 1 in 2.2 lbs = 1 kg 5 mL = 1 tsp 1 cup = 0.24 L 3.8 L = 1 gal 1. Directions: For all problems, show your dimensional analysis setup. Remember you can use the conversions shown above. Even if it is a metric conversion please practice with Dimensional Analysis, don't use "King Henry." Answers are provided at the end of each problem. They are underlined.
Dimensional analysis is a technique that uses the units (dimensions) of the measurement in order to correctly solve problems. Dimensional analysis is best illustrated with an example. Sample Problem: Dimensional Analysis. How many seconds are in a day? Step 1: List the known quantities and plan the problem. Known. 1 day = 24 hours; 1 hour = 60. Here's the conversion: 3.45 kg x 2.205 lb/kg = 7.61 lb. Dimensional analysis works because the given unit is always multiplied by a conversion factor that is equal to one. The conversion factor comes from an equation that relates the given unit to the wanted, or desired, unit. For example, the equation.

Dimensional Analysis is the use of unit (dimension) relationships to analyze a problem mathematically. This approach is logical and can be applied to many mathematical problems when relationships between units are known.
