Reacting masses Flashcards
1
Q
How can masses of reactants or products be calculated
A
This can be done by calculating the moles then using mole ratio to calculate amount of other species
2
Q
What is a solution
A
A solution is a homogeneous mixture of a solute and solvent
3
Q
What is concentration
A
Amount of solute that is present in a particular volume of solvent and has units of gdm^-3 or moldm^-3
4
Q
How can we go from gdm^-3 to moldm^-3
A
From gdm to moldm ÷ by Mr
From moldm to gdm × by Mr
5
Q
How to calculate moles in a a solution
A
(Concentration× volume)/1000
6
Q
What can mass/Mr also =
A
Mass/Mr=(c×v)/1000
