Chromium-51 is a radioisotope that is used to assess the lifetime of red blood cells The half-life of chromium-51 is 27.7 days. If you begin with 45.7 mg of this isotope, what mass remains after 49.3 days have passed? mg
Added by Gregory R.
Step 1
3 days using the formula: \[ \frac{N}{N_0} = \left(\frac{1}{2}\right)^{\frac{t}{t_{\frac{1}{2}}}} \] where: - \( N \) is the final amount of chromium-51 after 49.3 days - \( N_0 \) is the initial amount of chromium-51 (45.7 mg) - \( t \) is the time elapsed Show more…
