Chemistry Stiginometry study guide for test 4/30/2026 (I will need to take it another day)

for study :)

Percent yield equation

Actual over Theoretical times 100

How to find the theoretical yield

Maximum yield of specified compound using the limiting reactant in grams

Where to find the actual yield

The actual yield is usually given in the problem.

How to solve when there is an unknown element

make a train track that equals the given element, with the specified element at the start, using a variable for the unknown value. Solve what you can, then solve for the variable.

How to find the amount consumed, produced, or used of an element

Convert given element into the specified element in a train track using mole ratios.

What is used to convert one element to another?

mole ratios in train tracks

Percent Yield definition

How much was actually obtained compared to the maximum possible amount

How to find the mass of the remaining excess reactant

Convert Limiting to Excess and subtract from the total excess reactant

How to find Limiting and Excess Reactants

Convert both reactants to the same product in two train tracks, the lower number is limiting, and the higher number is Excess.

How to find the maximum amount of a product that can be produced?

convert the limiting reactant train track answer into grams

Liters STP to mole conversion

22.4L

Molecules to mole conversion

6.02 x 10^23 molecules

Grams to mole conversion

molar mass

If mole is mentioned twice

one conversion is needed

If mole is mentioned once

two conversions are needed

If mole is not mentioned at all

three conversions are needed
