Important Constants: 1 mole = 6.022x1023 particles 1 mole = 22.4 L for gases at STP
Grams to Particles Conversions
Step 1: Put your molar mass in the bottom of the equation, to divide by it and cancel out grams. 1 mole goes on top.
Example: How particles are there in 28 grams of Carbon? Molar Mass = 12.01 g/mol
_____ g of Carbon
_____ moles
_____ g of Carbon
Step 2: Put 1 mole in the bottom of the equation to cancel out moles. Put 6.022x1023 particles on top.
Example: How particles are there in 28 grams of Carbon? Molar Mass = 12.01 g/mol
_____ g of Carbon
_____ moles
_____ particles
_____ g of Carbon
_____ moles
Step 3: Multiply the top together, multiply the bottom together, take the top divided by the bottom.
Example: How particles are there in 28 grams of Carbon? Molar Mass = 12.01 g/mol
_____ g of Carbon
_____ moles
_____ particles
=_____ particles of Carbon
_____ g of Carbon
_____ moles
Example: How many particles in 95 g of Aluminum? Molar Mass = 26.98 g/mol
Particles to Grams Conversions
Step 1: Put your 6.022x1023 particles in the bottom of the equation, to divide by it and cancel out particles. 1 mole
goes on top.
Example: What is the mass of 2.8x1025 particles of Nitrogen? Molar Mass = 14.01 g/mol
_____ particles of Nitrogen _____ moles
_____ particles of Nitrogen
Step 2: Put 1 mole in the bottom of the equation to cancel out moles. Put molar mass on top.
Example: What is the mass of 2.8x1025 particles of Nitrogen? Molar Mass = 14.01 g/mol
_____ particles of Nitrogen _____ moles
_____ g of Nitrogen
_____ particles of Nitrogen _____ moles
Step 3: Multiply the top together, multiply the bottom together, take the top divided by the bottom.
Example: What is the mass of 2.8x1025 particles of Nitrogen? Molar Mass = 14.01 g/mol
_____ particles of Nitrogen _____ moles
_____ g of Nitrogen
=_____ g of Nitrogen
_____ particles of Nitrogen _____ moles
Example: What is the mass of 7.5x1024 particles of Zinc? Molar Mass = 65.39 g/mol
