I've been trying to figure this out for days...

sweetburger · Answer

you could write a linear equation using the data. although im not sure thats the correct way to go about it.

cometailcane · Answer

I came up with y= -0.0472/55 x +0.0927
It worked when I had to find the concentration at 48 seconds but I keep getting the wrong answer for 2 days.

jiteshmeghwal9 · Answer

the only mistake in ur linear equation is that the slope u found is incorrect.

m=-0.001275
so the correct linear relation is $$c=-0.001275 t+0.0927$$where c is the concentration (in M) & t is the time (in minutes).

u r asked to find concentration after 2 days which means t=$48\times60$minutes

jiteshmeghwal9 · Answer

so put t=2880 min in the linear equation i made & u will get the correct answer.
