Question #184817

^{3}H decays with a rate constant of 0.0563/yr. What is the activity of a 0.699 g sample in curies?

Expert's answer

1 Ci = 2.79×10^{-6 } × moles × t_{1/2}

= 2.79×10^{-6}_{ } × "\\frac{0.699}{3}" × "\\frac{1n^2}{\\lambda}"

= 2.79×10^{-6 }× "\\frac{0.699}{3}" × "\\frac{0.693}{0.0563}"

= 8 × 10^{-6 } yr
