Calculations

?
concentration?
=amount of substance/ volume
1 of 9
percentage yield?
=yield from reaction/ max theoretical yield x 100
2 of 9
atom economy?
=(Mr of desired product/ sum Mr of all reactants) x100
3 of 9
why is is important to consider atom economy?
- raw materials are expensive, if most are converted into waste products it is not profitable
-it is not sustainable to use large quantities of reactants to form tiny amounts of products
- waste products are expensive to dispose of
4 of 9
what is a solution to the problems of atom economy?
- using a more efficient reaction
-finding a use for the waste products (useful by-products)
5 of 9
moles?
mass/ Mr
6 of 9
density?
mass/ volume
7 of 9
1dm3 is how many cm?
1000cm3
8 of 9
rate of reaction?
= total products formed/ time
=total reactants used/ time
