You will need to create a ratio (conversion factor) between the units given and the units needed. Ask yourself which unit is bigger. Put a "1" by that unit. Then ask how many of the smaller units are in the bigger unit. Put that number in front of the smaller unit. There is your conversion factor.

When setting up a conversion factor to or from a base unit, use 1 for the prefixed unit and the power of 10 in front of the base unit. Example: 1 mg = 10-3 g; 1 kg = 103 g. Enter 103 in your calculator by typing 1 E 3 (using a button labeled E, EE, or EXP).
Step 1: Set up the ratio → (1 mg / 0.001 g) ÷ (x / 1 g) Step 2: Crossmultiply → (1 mg)(1 g) = (0.001 g)(x) Step 3: Isolate x → (1 mg)(1 g) / (0.001 g) = x
15 Σεπ 2022 · Conversion factors are used to convert one unit of measurement into another. Dimensional analysis (unit conversions) involves the use of conversion factors that will cancel unwanted units and produce the appropriate units.
Conversions between moles and grams of a chemical can be done by using molar mass, which is the addition of the atomic masses of the atoms making up that molecule. Atomic mass is the mass in grams of 1 mole, 6.022 x 1023 atoms, of an element. These atomic masses are listed on most periodic tables.
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. As an
