The answer is 2.
If after one half-life only half of the element remains, then after another half-life half of what was there only remains. So a half of a half is a quarter (or a fourth). So that's 2 half-lives.
Half-life time of a radioactive element is the time required for the decomposition of half of the actual mass of the element."Half life of radon is 3.8 days."This means that a particular mass of radon is reduced to half its mass in 3.8 days. The half-life period of an element does not depend upon the original mass of the element. This means that 10gms of radon will become 5gms of radon is 3.8 days, and 80gms of radon will become 40gms in 3.8 days.
An eighth.
The half life is the time it takes for half the atoms in a given sample to decompose. Knowing this then after 27 days there is half the amount left. After 54 days then there is half that half left so that's a quarter.
"ferrum" not "ferium" is the Latin name of iron, and an alternative name for this element, OR "fermium" not "ferium" is the name of an artificial element, named after the physicist and chemist Enrico Fermi. It is element 100. Its longest-lived isotope, Fm-257, has a half-life of 100 days.
A watch with 39 days on it could be a novelty or a special design feature rather than a practical display of time. It may not accurately reflect timekeeping but could be a unique way of representing the passing of days or simply serve as a creative design element.
120. 10 milligrams twice a day would be 20 milligrams a day. 20 milligrams a day/ 5 milligrams in a tablet = 4 tablets a day. multiply that by 30 days and you get the answer.
Milligrams in a carat.
7-14 days
If it is an electric hot water tank, you more than likely have a burnt out element
.05 grams = .05(1000) = 50 milligrams 3(50 milligrams) = 150 milligrams 150 milligrams/25 milligrams = 6 So you should order six 25 milligram capsules This answer is only sufficient for 1 day. The physician wants 50 mg three times a day for 2 days which is 300 mg = 12 capsules. Patent takes 2 capsules at each dosage time. Brian Jones
i need to mknow because my father was charged with murder of my mom and he didnt do it and there was 8 milligrams of strychnine in her blood.
The most important element for survival is water. We can survive days on water alone if food were not available. Therefore, settling near water was/is necessary.
Detox for 7 days. Then you'll be clean
I am available on the following dates.
This sounds like a job description. It means you will work three days out of the week to start with.
After 32 days, approximately 5 milligrams of the 80-milligram sample of Iodine-131 would be left. Iodine-131 has a half-life of about 8 days, so after each 8-day period, half of the remaining sample will decay.
Latter Days is available from NetFlix.
