The ratio between the number of tritium (13T; radio active isotope of hydrogen) and the naturally occurring isotope H is n(T) : n(H) = 1 : 1019 and the half-life of tritium is 12.5 years. Given that the molar mass of water is 18.02 g/mol, how many grams of water is needed to to observe 10 tritium decay events in one hour?
