New cards

Concentration

Ratio between solute+solvent

2
New cards

Dilute

Small ratio of solute to solvent

3
New cards

Concentrated

Large ratio of solute to solvent

4
New cards

Standard mL of solvent

100mL

5
New cards

% concentration formula

% concentration= Quantity of solute/Quantity of solvent x 100

6
New cards

3 main types of concentration ratios

-%V/V (mL/mL)

-%M/M (g/g)

-%M/V (g/mL)

7
New cards

Parts per million/billion concentration

-M/M ratio used for extremely low concentrations

-1ppm=1mg/1kg

8
New cards

ppm concentration formula

ppm concentration= m(solute)/m(solution) x 10^6 ppm

9
New cards

ppb concentration formula

ppb concentration= m(solute)/m(solution) x 10^9 ppm

10
New cards

Water unit conversions

-1mL=1g

-1kg=1L

11
New cards

Molar concentration formula

Molar concentration ( c ) = mol of solute (n) / volume of solvent (L)
