The half-life of radium is about 1600 years. If a rock initially contains 1 g of radium, the amount left after 6500 years will be about: A 0.016 g B 0.032 g C 0.061 g D 0.046 g E 0.098 g F 0.082 g

Radium-226, a radium isotope, has a half-life (the time it takes for half of the isotope to decay) of about 1620 years. 30 grams is the mass of the sample. Which of the following equations expresses the number of grams of radium-226 that will be left after t years?

The half-life of radium-226 is 1600 years. Suppose we have a 26-mg sample. How much of the sample will remain after 4500 years? (Round your answer to one decimal place.) (hint: function m(t) = m0e^-rt models the mass remaining after t years.) A. 3.70 B. 2.8 C. 2.1 D. 36.6

The half-life of radium is 1600 years. The number of atoms that will decay from $1 \mathrm{~g}$ sample of radium per second is (Given: Atomic weight of radium $=226$ ) : (a) $3.6 \times 10^{10}$ (b) $7.2 \times 10^{10}$ (c) $4.2 \times 10^{10}$ (d) $14.6 \times 10^{10}$
