The table below compares the radioactive decay rates of two materials. Material Original mass of material (in grams) Mass of material after 60 hours (in grams) 1 208 13 2 200 50 Based on the table, which of these conclusions is most likely correct? The half-life of Material 1 and Material 2 are equal. The half-life of Material 2 is double the half-life of Material 1. The half-life of Material 2 is 30 hours more than the half-life of Material 1. The half-life of Material 1 is 30 hours more than the half-life of Material 2.

    OK. So far i've got that the Half life of Mat. 1 Decays every 15 hours Because it decayed Four times. Mat. 2 decays every 30 Since it decayed twice...
