Determine the age of a rock containing 0.065 g of uranium-238 (t12 = 4.5 x 10°yr) and 0.043 g of lead-206. (Assume all the lead-206 came from 238U decay.) Enter your answer in scientific notation. 2 68 x 10 irs old h
10. A rock contains 270 micromoles of U-238 and 110 Micromoles of Pb-206. Assuming that all the Pb-206 comes from decay of the U-238, estimate the rock's age.
Determine the age of a rock containing 0.065 g of uranium-238 (112 = 4.5 x 10° yr) and 0.046 g of lead–206. (Assume all the lead-206 came from 238U decay.) Enter your answer in scientific notation. x 10 years old
Enter your answer in the provided box. A rock sample originally contains 4.10 mg of 238 U. How much 206 Pb will be in the rock sample when it is 3.2 × 10^ 8 years old? The half-life of uranium \−238 is 4.51 × 10^ 9 years.
