first year
aight
so you can help me with basic stoichiometry
gimme a minute
my dog is yelling
Kappa
KappaG How long as this existed
4 hours?
Yeah not long
aight
so idk if im doing any of this right
I do not know if you are doing any of that right either
post the question
stoichiometry is basically all ratios
fucking
Post one someone without 40/20 vision can read
Also nice knees
thanks
i think you are doing molarity wrong
sounds about right
Noice KeyBoard lewd
That better?
second from the bottom should be .2 mol if M is 2.5
For the clast one, you can use the equation C1V1=C2V2, which is the dilution formula
im in sophmore chem
C1V1 being inition concentrations and volumes respectively
idk what that is
Fucking
i know the basic chart
The moles should be constant
Where n is moles
i think you are making this more complicated than it should
So the initial concentration and volvime (C1V1), should equal the final C2V2
i know M=n/v
so you basically have 2 equations
of M=n/v
.125/.05=2.5
where n is the same for both
wait for second to last
or last
second to last should be .2
.125/.05=2.5
molarity uses L right? not mL?
2.5M/L =.2mol/.5
it's interchangeable
50mL is 0.5L
unless I am stupid
you are stupid i think?
0.05
oh okay
I am stupid
I am bad at unit conversion
1000l per ml
wait
backwards
other way around
yeah
okay, yeah, you were right
my bad
so second one
man 3 idiots can't solve a math problem
i have .125=n/.25 for one and .5=(same n)/x
says alot about us Kappa
This is interesting
Last one is correct if what you wrote was 62.5mL
ok good
the one on the last page im pretty confident in
I can not read anything above second last
thats fine
