Atom Economy | GCSE Chemistry Practice
Atom economy measures the proportion of starting materials that become useful products.
Why is a high atom economy important for sustainable development?
What is Atom Economy | Practice?
"A measure of the amount of starting materials that end up as useful products."
Calculate the relative formula mass (Mr) of H2O. (H=1, O=16)
Calculate the mass of 0.25 moles of Calcium Carbonate (CaCO3). (Mr=100)
How many moles are in 36g of water? (Mr of H2O = 18)
Which formula is used to calculate the number of moles?
Sustainable Chem
Atom Economy = ($M_r$ of desired product / sum of $M_r$ of all reactants) x 100.
High atom economy means less waste and better use of resources.
A reaction with only one product always has 100% atom economy.
Sustainability: Improving atom economy is a key goal of "Green Chemistry" to preserve raw materials.
