100
The number of atoms or molecules in 1g of hydrogen or 12g of Carbon.
What is a mole?
100
When do we compare the mass of the empirical formula to the mass of the compound and then multiply/divide accordingly?
What is finding the molecular formula?
100
The answer when converting 1.00g of Hydrogen and 16.0g of Oxygen into moles.
What is 1 mole of hydrogen and oxygen

Amedeo
What was Avogadro's first name?
200
Mass of a mole of a chemical substance
What is molar mass?
200
The mass present and this is required for calculating the empirical formula.
What is the relative mass of the element?
200
The answer when converting 8.02x10^23 atoms of Iron to moles.

6 x 1023
What is Avogadro's number?
300
Mass Used/ Molecular mass
How do you calculate the amount of moles?
300
A formula giving the proportions of the elements present in a compound but not the actual numbers or arrangements of atoms.
What is the empirical formula?
300
It's used to determine the concentration of an unknown substance.
What is Volumetric analysis?
300
24 dm3
What is r.t.p's volume?
300
At the same temperature and pressure, equal volumes of all gases contain the same number of molecules.
What is Avogadro's Law?
400
mol
What is the shortened form of the unit for the mole?
400
A chemical formula based on analysis of empirical forumla and molecular mass.
What is molecular formula?
400
Also called Molarity
What is Molar Concentration?
400
22.4 dm3
What is s.t.p's volume?
400
Divide by Avogadro's number.
What is the calculation to know how many moles of atoms are present in a number of atoms?
500
To make it easier to count atoms as they are in abundance and too much to count.
What is the reason for the mole?
500
One has the smallest whole number for their subscript whereas the one is the actual number of molecules or atoms in a compound.
What is the difference between the empirical and the molecular formula?
500
This of a compound is a relative measure of the mass (in %) of each different element present in the compound.
What is Percentage Composition?
500
273 K (0° Celsius) and 1 atm pressure.
What does S.T.P correspond to?
500
A hypothetical gas whose molecules occupy little to no space and have no interactions, and which obey the gas laws exactly.
