Every time a period of time equal to the half-life passes, there will only be half as much material left as there was before.
In this case, three years represents 3 ÷ 0.75 = 4 half-lives.
As a result, the remaining amount has been cut in half four times:
1 2 × 1 2 × 1 2 × 1 2 = ( 1 2 ) 4 = 1 16 
There is 1 16 of the original amount, which is
230 × 1 16 = 14.375 g
