I have a question Iam stuck on. I was wondering if i did the right calculations. Please let me know:(adsbygoogle = window.adsbygoogle || []).push({});

Through decay, Chemical Q loses one-third of its mass every 7 years.

Twenty-five years ago, a container of Chemical Q was buried. The EPA has

just dug it up and found 1,000 grams remaining. How much Chemical Q was

originally buried?

1000=(Q)(1/3)^(x/7) when x = 25

1000=(Q)(1/3)^(25/7)

Q = 1000/(3)^(3/7)/81

Q = 50583???

I am not sure if I did this correct??
