1M
1moldm^-3 = 1molL-1
1 mol
how many particles/molecules of a particular substance in a solution = Avogadro’s constant
Avogadro’s constant
how many particles/molecules of a particular substance in a solution (1 mol)
1M value
6.02x10^23 (Avogadro’s constant)
what does something being more dilute mean?
less concentrated
how do we make a substance less concentrated?
dilute it
how do we know if something is more dilute/less concentrated than another?
smaller number
what’s the most accurate way to dilute a solution?
make one concentrated solution and dilute it (make it less concentrated)
dilution equation
C1V1 = C2V2
organ bath
tube with solution and tissue in it
name for the starting drug solution
stock solution
stock soluton
name for the starting drug solution
10ml in mM
10
10mM in ml
10
what can V2 be in C1V1 = C2V2?
how much you add
(you don’t have to add it to the original volume - there’s only a small error)
fold equation
x fold = starting conc./x
what is %w/v for?
expressing solution concentration in terms of % (weight/volume)
what does the % in w/v tell us?
how many g in 100ml
100microL in ml
0.1
0.1ml in microL
100
when are logarithms particularly useful?
for interpreting graphs better
anti-logs
10^x
explain how to do log101microM
log of a micromolar
micromolar = 1x10^-6M
= -6 (same as the prefix value)
Equation for working out the concentration of a new solution
Starting concentration/x
(For an x fold dilution
