Answer:
146.63 grams.
Step-by-step explanation:
The mass percent that remains after every minute is 100%-18.8 = 81.2% of the initial mass. This means after 1 minute the mass remaining is
![630*0.812](https://tex.z-dn.net/?f=630%2A0.812)
After 2 minutes, the mass reaming is
![(630*0.812)*0.812](https://tex.z-dn.net/?f=%28630%2A0.812%29%2A0.812)
After 3 minutes
![(630*0.812*0.812)*0.812](https://tex.z-dn.net/?f=%28630%2A0.812%2A0.812%29%2A0.812)
so we see the general pattern: the grams remaining after
minutes are
![\boxed{ 630 (0.812)^m}](https://tex.z-dn.net/?f=%5Cboxed%7B%20630%20%280.812%29%5Em%7D)
Now after 7 minutes the grams remaining are
![630(0.812)^7=146.63](https://tex.z-dn.net/?f=630%280.812%29%5E7%3D146.63)
146.63 grams.

<em>Comment on the question</em>
Vectors can be represented a number of different ways. Components can be given in rectangular or polar form, and the presentation can be made as a row vector, column vector, sum of orthogonal unit vectors, and other ways. We assume this is supposed to be a column vector of the form ...
