First, we separate all instances of t by subtracting J from both sides:
F = J + Jrt
F - J = Jrt
Then, we separate the t by dividing both sides by Jr:

Therefore, t is equal to (F - J) ÷ Jr

The formula for percent error is: (M-A)/A x 100
M= the amount of the sample measured
A= the exact value of the sample
And the value of M-A is always positive
So, 2.75-2.699= .051g/cm3, and .051/2.699=.01889
.01889 x 100=1.889% or 1.9% error
