How much of a 100 gram sample would remain unchanged after two hours?
This would depend on the specific sample and its stability. Without additional information, it is not possible to determine how much of the sample would remain unchanged after two hours.

How much cesium would remain from a 10g sample after 4 years?
I suppose that you think to the radioactive isotope Cs-17; After 4 years remain 9,122 g.
How much would remain from a 10 g sample after 6 years?
You must know the half life of Caesium to calculate this.
If you had a 100 gram sample of plutonium how much would remain in 43 years?
Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay. In 43 years, which is much shorter than the half-life, only a tiny fraction of the plutonium would decay. Therefore, after 43 years, approximately 99.83 grams of the original 100-gram sample would remain.

How much of an 800-gram sample of potassium-40 will remain after 3.910000000000 years of radioactive decay?
Approximately 400 grams of the potassium-40 sample will remain after 3.91 years, as potassium-40 has a half-life of around 1.25 billion years. This means that half of the initial sample would have decayed by that time.
