Why is it necessary to convert given units of substances to moles when solving a stoichiometry problem?

We convert units to moles because in reactions atoms of different elements combine in simple whole-number ratios. The whole numbers are related to the number of atoms, not their weights.

How can you identify a stoichiometry problem?
When a problem has a label "stoichiometry" on top of it.
What is the problem solving method in chemistry that uses mathematical relationships to convert one quantity to another?
Factor Label Method
What value is needed to convert mass to volume in stoichiometry problem?
Density (at a given temperature) is the parameter that relates the mass to the volume of any substance.
What is molar mass's role in reaction-stoichiometry?
Stoichiometry is based on the fact that chemical reactions occur in ratios of moles of all substances. The problem is that there is no device that directly measures moles. We do have a device to measure mass, so molar mass is used in stoichiometric calculations to give results which are measurable.
How do you solve this partial pressure stoichiometry problem?
Well, first you start with a problem . . .

What is the first step in solving a problem in stoichiometry?
Balance the number of atoms for each element on both sides of a chemical equation
What are the answers to Holt chemistry's stoichiometry problem solving packet?
Na2CO3+2H(C2H3O2) >2Na(C2H3O2) + CO2+H20
How do you solve stoichiometry?
You don't solve stoichiometry. The questions and answers that arise in stoichiometry are merely manipulations of permanent relationships between things (e.g. there are approximately 70.9 grams in one mole of chlorine gas). The conversions needed to report an answer of a stoichiometric problem are the part that take work to overcome mentally. One has to evaluate the units that a value starts with and the units the final answer requires and think about what conversions are needed in between.
How do you calculate word problems?
You convert the word problem into a numeric problem and then calculate.
Which advice would be least helpful to the writer of a problem-solution essay?
If your reader knows the problem, it's not necessary to state it
How many kg of oxygen are consumed when sufficient ammonia NH3 is catalytically oxidized to produce nitric acid HNO3 and 402 kg of water?
You need to write a balanced reaction and then use stoichiometry to solve this problem.First write a balanced reaction. The reactants are O2 and NH3 and the products are HNO3 and H2O. For step-by-step instructions on how to balance a reaction, see the Related Questions link to the left.Then use stoichiometry to solve the problem. See the Related Questions to the left for step by step instructions on how to do that! And don't forget to convert the 402 kg of water into moles!
Do you hyphenate problem solver?
No hypen is necessary.
