The half-life for the radioactive decay of C−14 is 5730 years.
If a sample of C−14 initially contains 1.7 mmol of C−14, how many millimoles will be left after 2250 years? Express your answer using two significant figures.
Homework Answers
HL = 5730
[C1] = 1.7 mmol of C14
[C2] = ?
t = 2250
apply half life equation
[C2] = [C1]*(1/2)^(t/HL)
substiutte all that
[C2] = (1.7)(1/2)^(2250/5730) = 1.2949
[C2] = 1.29 mmol
