How much cesium half life 2 years would remain from a 10 g sample after 6 years?

The formula for finding the amount of radio active substance that remainsafter decomposition is A = N(1/2) ^y, where A is the mass remaining, N is the original mass of a radioactive sample and y is the number of half life. In this case, N = 10 g and y = 6/2 = 3. So A is given by 10 x (1/2)^3, which is 10 x 1/2 x1/2 x 1/2 = 1.25 grams.

∙ 6y agoLet's work it out. Since the half life is 2 years, the 6 yr span is 3 half life periods. Starting with 10 grams, after the first period (2 years) you will have half of the 10- or 5 grams. After the second period (4 years elapsed) you lose half of what you had- 5 becomes 2.5 After the final period (6 yrs) half of the 2.5 is gone, leaving 1.25 grams.

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.

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.
