3200 ÷ 2 = 1600 Note: 50% is half of something.
How many grams of radium-226 will remain from 5 grams after 365 years if the half life of radium 226 is 1600?
The question, as posed cannot be answered because you have not stated the units for the half-life. Some things have half lives of millions of years while others have half-lives measured in micro-seconds. Fortunately, Wikipedia came to my rescue and the half-life is 1600 years (approx). The answer is approx 4.3 grams.
What is 2.9 percent of 1600?
2.9% of 1600= 2.9% * 1600= 0.029 * 1600= 46.4
What is 35 percent 0f 1600?
35% of 1600= 35% * 1600= 0.35 * 1600= 560

How can an element with a half life of 1600 years still be around?
The isotope must still be being created through the decay of other elements into this one. Also, small quantities throughout the universe may still exist from their creation in supernovas or even the Big Bang, because of the concept of a half-life. Half would've decayed in the first 1600 years, then another half in the next 1600, but there are so many atoms in even a kg of material that some still may not have decayed yet, through many increments of 1600 years.
If Ra-226 had a f life of 1600 years and you have 20 grams how much will be left in 3200 years?
I will try to make the answer simple for you. Half life is 1600 years. So After 1600 years you have half the mass left. That is 10 grams. After another 1600 years, you will be left with half the mass of 10 grams. That is five grams. So after total 3200 years you will be left with 5 grams of mass of the Ra-226 left with.
What is 50 percent of 3200?
3200 ÷ 2 = 1600 Note: 50% is half of something.
