Polonium-210 is a radioactive substance with a half-life of 138 days. If a nuclear facility is handling 190 grams of polonium-210, then how many grams of polonium-210 will be left in 230 days.

We have been given that Polonium-210 is a radioactive substance with a half-life of 138 days. A nuclear facility is handling 190 grams of polonium-210. We are asked to find the grams of polonium-210 will be left in 230 days.

We will use half-life formula to solve our given problem.

, where,

= Final amount,

= Initial amount,

t = Time,

h = Half life.

Upon substituting our given values in half-life formula, we will get:

To find the grams of polonium-210 will be left in 230 days, we will substitute in our formula as:

Upon rounding to nearest hundredth, we will get:

Therefore, approximately 59.85 grams of polonium-210 will be left in 230 days.
