moles Flashcards
1
Q
moles in solute equation
A
n= m/ Ar or Mr
2
Q
% yield
A
shows how much product was actually made compared with amount of product expected
3
Q
% yield equation
A
% yield = actual/theoretical x 100
4
Q
how to calculate actual and theoretical values
A
theoretical- calculated/expected
actual- from actual reaction
5
Q
why % yields are less than 100
A
loss of product (transfer)
incomplete reactions
by products
6
Q

A
6.023 x 1023
7
Q
molar volumes
A
moles = volume of gas / V mol(24dm3)
8
