Calculate k.
k = 0.693/t(1/2)
Then put k into the following:
ln(No/N) = kt
No = 6.90 g
N = solve for that.
k = 0.693/t(1/2)
Then put k into the following:
ln(No/N) = kt
No = 6.90 g
N = solve for that.

For the 1 yr it's about 6 g remaining.
For the 10 yr it's 2 g remaining.
Post your work and I'll find your error.
