The nuclide ratio, ""_1^3H to ""_1^1Hin a sample of water is 8.0 xx 10^(-18): 1. Tritium undergoes decay with a half-life period of 12.3 years. How many tritium atoms would 10.0 g of such a sample contain 40 years after the original sample is collected? |

Answer» Solution :Given that , `("MOL of " T_2O "molecules")/("mol of " H_2O" molecules") = (8 xx 10^(-18))/(1)` ` THEREFORE 10g` of SAMPLE contains `(2 xx 8 xx 10^(-18)) xx 10/18` mole tritium atoms` `5.62 xx 10^5` |
