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
im pretty confident in those
it ust felt wierd on the second to last one where it was like, a 1 line equation with all that space
Now you should solve my equivilence point calculations for my titration Kappa
i made a molar mass calculator in excel which is useful
first i made a separate sheet with all the masses in the periodic table, then used this for a 4 element calculator
=index(MassData!A1:B110,match(B41,MassData!A1:A110,0),2)B42+index(MassData!A1:B110,match(C41,MassData!A1:A110,0),2)C42+index(MassData!A1:B110,match(D41,MassData!A1:A110,0),2)D42+index(MassData!A1:B110,match(E41,MassData!A1:A110,0),2)E42
Seems like a lot of work tbh
Clearly you just need to integrate the change in mass to find the mass for which the total moles is equal to avagadros number, then calculate from there Kappa
Also I like how you only show up for homework assistance Kappa
Potahto is a Unique Person Kek
at least he actually talks here
instead of lurking
i mean like
i occasionally talk
usually it is homework tho
primarily math and chem
i thought you said primarily meth and children for a second
go home karp
Well, I am good for math, chem not so much
you are drunk
