Quantitive Chemistry Flashcards
1
Q
What is the equation linking concentration, volume, and mass
A
Mass(g)=concentration(g/dm^3)*volume(dm^3)
2
Q
What is relative formula mass
A
Sum of relative atomic masses of all atoms in formula of a compound
EG: CO2= 12+(2x16)=44
3
Q
How do you calculate uncertainty?
A
Half the range of values
EG Volumes:12.5,12.3,12.6=+/-0.3
4
Q
What is the value of a mole?
A
Mol=6.02x10*23 particles
5
Q
What is 1dm^3 in cm^3?
A
1000cm^3/1L
6
Q
Equation:Mass,Mr,Mol
A
Mass(g)=MrxMol
7
Q
Def:Limited Reactant
A
Reacting species completely used up. Determines amount of product formed.
8
Q
Def: Excess
A
More of it than needed to react
9
Q
what does the conservation of mass state
A
the total mass of the product must equal that of the reactant
