As you did not specify an isotope of cesium, I will assume you meant natural cesium. Natural cesium is not radioactive so it does not decay.
There will always be the same 10 g of cesium, no matter how long you wait.

While the other guy is right, you forgot to add the part that says the given half-life is 2 years. This means there will be 2 1/2 grams left

How much cesium would remain from a 10 g sample after 2 years?
5g would remain
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 cesium(half life2 years) would remain from a 10 g sample after 4 years?
2 1/2 g
how much cesium (half-life = 2 years) would remain from a 10 g sample after 2 years?
2 1/2 g
How much cesium with a half life 2 years would remain from a sample after 4 years?
The equation for half-life is ... AT = A0 2 (-T/H) ... where A0 is the starting activity, AT is the activity at some time T, and H is the half-life, in units of T. 55134Cs has a half-life of 2.0652 years. Plugging in the known values, we get ... AT = 5.8 2 (-11.5/2.0652) AT = 5.8 2 -5.5685 AT = 0.12222

How much cesium (half-life 2 years ) would remain from a 10 g sample after 4 years?
2 1/2 g
How much cesium (half-life = 2 years) would remain from a 10 g sample after 6 years?
1 1/4 g (apex)or 1.25 g
How much cesium would remain from a 10 g sample after 6 years?
You must know the half life of Caesium to calculate this.
How much cesium half-life 2 years would remain from a 10 g sample after 4 years?
2 1/2g
If 1.0 mg of cesium-137 decays over a period of 90 years how many mg of cesium-137 would remain?
Since the half-life of cesium-137 is about 30 years, 3 half-lives would have passed in 90 years. The first half-life would leave .5 mg of cesium-137. The second would leave .25 mg, and the third half-life would leave .175 mg of cesium-137.
If 12.5 grams of the original sample of cesium-137 remained after 90.69 years what was the mass of the original sample?
100g
