Nothing
Explanation:
Mass of the sample = 500g
Decay rate per anum = 11%
Unknown:
Mass of sample remaining after 10yrs = ?
Solution:
This is a simple percentages problem;
The radioactive sample loses 
x 500g of sample per year;
this is a loss of 55g per year;
In 10years time, the sample would have lost 10 x 55g = 550g of element.
Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.
