Answer to Question #184817 in General Chemistry for Juana Marshall
3H decays with a rate constant of 0.0563/yr. What is the activity of a 0.699 g sample in curies?
1 Ci = 2.79×10-6 × moles × t1/2
= 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
