you shoud try to ask it in chemistry section
ok thanks it scause i really need this answer
do you have the formula?
n is moles?
i need to round to the nearest hundreds too
what is the unity of k?
What does k represent?
a positive constant that depends on the substance itself and on the units used to measure time
5=10*e^(Kt), but what unity of time? seconds^-1?
Its in days
and probally the formula is e^(-kt)
did you see the picture
ya its a diff question :)
my bad ill got teh wrong one
if k is in days^-1 just solve 5=10*e^(-kt), and you will find t
but i dont know how to solve it either -.-
can you help me please i really need it
so the answer is 0,5
its exponoential decay thats the section were doing
i use that k
yeah k is that
it said its wrong -.-
we have to know thr unity of k
What did you put the answer as?
sorry I am not making sense. What did you enter as your answer?
Its to the hundredths place so it should be 5.12
try 1871.15 days
im supposing k is in years
Ohhhh yaaaaa that makes more sense actually
this is another question can you guys help with this one
please i did it
you guys help me i really did to passs this class tomorrow is my last day
are you guys there ?
