Transcript of A mole is not a furry rodent

A Mole Is Not a Furry Rodent The SI base unit of an amount of a substance. The amount of the substance equal in grams to the sum of the atomic weights
What is A mole? How to balance a chemical equation Step 1:
Start with a chemical equation Example:
C5H12 + O2 --> CO2 + H2O Step 11:
Balance the chemical equation Example:
C5H12 + 8O2 --> 5CO2 + 6H2O How to solve a word problem involving moles Example:
How many grams of carbon dioxide are produced from 4.5 grams of oxygen gas? Step 1:
Find the balanced equation Example:
C5H12 + 8O2 --> 5CO2 + 6H2O Step 11:
Set up an equation starting with the given amount to find the amount in moles (4.5g O2 x 1 mol O2) / (32g O2) = .14 mol O2 Step 111:
Set up an equation to find the number of moles of CO2 (.14 mol O2 x 5 mol CO2) / (8 mol O2) = .0875 mol CO2 Step 1v:
Set up an equation to find the mass of CO2 (0.875 mol CO2 x 44.01g CO2 ) / (1 mol CO2) = 38.51g CO2 Final Answer:
38.51g CO2 Cited Sources:
