The Mole
6.022 x 1023
What is Avogadro's constant/number?
The molar ratio comes from this.
What is the balanced chemical equation?
This is how we can find the molar mass of a compound
What is the sum of the atomic masses of the elements from the periodic table?
15 g of H2 equals this mass of hydrogen atoms
What is 15 g?
The molar mass of platinum.
What is 195.08 g/mol?
The ratio of hydrogen gas to water in water synthesis
What is 2:2 or 1:1?
How many grams of NH3 can be produced from the reaction of 10 g of N2 and 10 g of H2?
N2 + 3H2 --> 2NH3
What is 12.1 g of NH3?
All chemical reactions must follow this law
What is the law of conservation of mass?
mass of reactants = mass of products
6.25 moles of fluorine have this mass using this conversion
What is 6.25 mol Fl x 19.00g/1mol = 118.75g?
Creates the least amount of product. (also indicates which reaction actually happened)
What is the limiting reactant?
How many grams of H2 are needed to make 20 g of NH3?
N2 + 3H2 --> 2NH3
What is 3.6 g of H2?
The amount of grams of CO2 produced when 75 grams of carbon monoxide are burned in oxygen?
2CO + O2 --> 2CO2
What is 117.8 g CO2?
1.9 x 1022 atoms is this amount of moles using this conversion factor
What is 1.9 x 1022 atoms x 1 mol/6.022x1023atoms = 0.032 moles?
Challenge
