The number of `U^(238)` nuclei in a rock sample equal to the number of `Pb^(206)` atoms. The half life of `U^(238)` is `4.5xx10^(9)` years. The age of the rock is

The number of 238 U atoms in an ancient rock equals the number of 206 Pb atoms. The half-life of decay of 238 U is 4.5x10 9 years. Estimate the age of the rock assuming that all the 206 Pb atoms are formed from the decay of 238 U.

The number of 238 U atoms in an ancient rock equals the number of 206 Pb atoms. The half-life of decay of 238 U is 4.5x10 9 years. Estimate the age of the rock assuming that all the 206 Pb atoms are formed from the decay of 238 U.

The number of ^238 U atoms in an ancient rock equals the number of ^206 Pb atoms. The half-life of decay of ^238 U is 4.5 xx 10^9 y . Estimate the age of the rock assuming that all the ^206 Pb atoms are formed from the decay of ^238 U .

A sample of rock from moon contains equal number of atoms of uranium and lead ( t_(1//2)" for "U=4.5xx10^(9) years). The age of the rock would be :

The atomic ratio between the uranium isotopes .^(238)U and.^(234)U in a mineral sample is found to be 1.8xx10^(4) . The half life of .^(234)U is T_((1)/(2))(234)=2.5xx10^(5) years. The half - life of .^(238)U is -

A sample of rock from moon contains equal number of atoms of uranium and lead (t""_(1//2)for U=4.5xx10""^(9) year). The age of the rock would be

In an ore containing uranium, the ratio of U^(238) to Pb^(206) nuclei is 3. Calculate the age of the ore, assuming that all the lead present in the ores are the final stable product of U^(238) . The half-life of U^(238) is 4.5 xx 10^(9) years.
