Advanced Dimensional Analysis Flashcards
How to use the density of a substance in dimensional analysis
Put it over one and add units, this allows you to get volume out of grams.
If a unit is cubed or raised to a power…
You must cancel it out 3 times, And conversely you must use it a number of times to get to the desired unit to a power :0 yay
How to get moles of an element in the compound for example, moles hydrogen in ch3
You put the moles of the compound over the moles of the gas. As per the example, you pound put 1 mole ch3 over 3 moles hydrogen
At stp, a mole of any gas is equal to
22.4 liters
Molarity
Moles per liter, used as a conversion factor
How to do basic dimensional analysis?
Put the original value over one, and cancel values by aligning units and conversion factors.
How to do 2 or more step conversions
Just line up the units so they cross multiply and cancel out. and make sure that everything cancels out except your desired unit…. It isn’t too bad:)
