see Sidiqi's post below
I got 0.193 half-lives. Does this answer make sense??
makes sense to me. After 1 half-life there will only be 500 atoms, so it will be less than that.
Your answer is correct.
Your answer is correct.
there will be three half lives when sample is decreased from 1000g to 875g.....
