The half life of ._(92)^(238)U is 4.5 xx 10^(9) years. Uranium emits an alphaparticle to give thorium. Calculate the time required to get the product which contains equal masses of thorium and uranium. |

Answer» SOLUTION :`N_(0) = (1)/(238) + (1)/(234)`,`N = (1)/(238)` Use, `(0.693)/(t_(1//2)) = (2.303)/(t) log_(10) ((N_(0))/(N))` |
