If they have a long halflife, you can tell how much time has gone by since the element last has changed on earth.
Answer:
365.212
Explanation:
According to the given situation, the calculation of molar mass is shown below:-
Data provided
![c_{16}\ h_{19}\ n_3\ o_5\ S](https://tex.z-dn.net/?f=c_%7B16%7D%5C%20h_%7B19%7D%5C%20n_3%5C%20o_5%5C%20S)
Molar mass = 16 × 12 + 19 × 1.008 + 3 × 14 + 5 × 16 + 32.06
= 192 + 19.152 + 42 + 80 + 32.06
Molar mass = 365.212
Therefore for determining the molar mass we simply solve the above equation.
So, the correct answer is 365.212
