you can use it to measure the mass of a sample of matter.
how does the knowing of the size of a mole help with problems in chemistry?
100
Stoichiometry
What is the study of a quantitative relationships between reactants.
200
Stoichiometry
A samples mass or volume can be converted to a count of the number of its particals such as atoms, ions, or molecules, is an example of what?
200
CO2(g)+3H2(g)-->CH3OH(l)+H2O(g). the equaltion relates to what?
What is the reactants and products
200
the volume that a mole of gas occupies at a pressure of one atmosphere and a temperature of 0.00' C
What is the Molar Volume?
300
By using Avogadros Number
how are submicrocopic particals counted?
300
how else can you find the molar mass of an atom?
What is find is atomic number
300
The ratio of actual yield (from an experiment) to a theoretical yield (from stoicchiometric calculations) expressed as a percent.
What is Percent Yield?
400
1 Balance the equation.
2 Convert units of a given substance to moles.
3 Using the mole ratio, calculate the moles of substance yielded by the reaction.
4 Convert moles of wanted substance to desired units.
What are the steps to set up a Stoichometry problem?
400
is the molar mass in the mass of grams? True or false.
What is True
400
the number of things in one mole of a substance, specifically 6.02 x 10 to the 23rd.
What is Avogadro's Number?
500
Moles = Grams / Gram formula Mass
What is the gram formula mass that can be used as a conversion factor in stoichiometric calculation?
500
The ratio of moles of what you've been given in a reaction to what you want to find.
What is the mole ratio?
500
the equation that expresses exactly how pressure P, volume V, temperature T, and the number of particals n of a gas are related. PV=nRT.
