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.

The radioactive substance Carbon-14 has a half life of 5730 years. After 1000 years there is 2.66 grams remaining. What was the initial amount of the substance?
3.002 grams, approx.
How much rubidium-87 would remain in an object that is 147 billion years old?
Rubidium 87 has a half life of 49 billion years so it would be 3 half lives. There should, therefore be 1/8 remaining. However, it is believed that the universe is less than 15 billion years old. So finding any object that is 147 billion years old is - to put it mildly - totally impossible!
What fraction of the original c14 would you expect to be present in a fossil that is twenty eight thousand six hundred and fifty years old?
The half-life of C14 is 5730 years so the given period is 5 half-lives. You should, therefore, expect approx 2-5 = 0.03125 of the original C14 to remain.

What fraction of radium will last for 3240 years?
Radium has a half life of 1601 years. So 24.6% will remain after 3240 years.
How many grams of a 35 gram sample of radium will decay in 5000 years if the half-life of radium is 1602 years?
approx. 31 g.
What fraction of a radium sample will remain after 3240?
The answer depends on 3240 WHAT: seconds, days, years?
How many grams remain after 20 years?
100 grams
Radium-226 has a half-life of 1602 years. If you start out with 15 grams of radium-226 how much will be left after 3 half-lives?
1.875g
If a sample contains 100g of a radioactive isotope how much will be left after 3 half lives?
There will be 125 grams of radium left. Keep it simple. Ih a half-life, half the sample decays. Half of 1000 grams is 500 grams, then half of 500 grams is 250 grams. Half of that again is 125 grams. And just so you know, the half-life of radium-226, the non-synthetic isotope of radium, is 1602 years. If this was the case here, 4806 years would have to pass to get the sample to decay as far as it did.The remained quantity of radium after 3 x 1602 years is 125 grams.
How many milligrams of a 15.0 mg sample of radium-226 remain after 6396 years if the half-life of radium-226 is 1599?
One sixteenth of a gram. 1st halflife- 1/2 gram 2nd, 1/4 3rd 1/8th 4th halflife, 1/16th
What is the international price of radium power?
There is no specific price for radium power. However the price of a pound of radium is $50,000,000. Radium prices have decreased over the years.
If the initial quantity is 5 grams how much remains after 600 years?
That depends what assumptions you make about what the 5 grams of matter is made of.
How much of an 800-gram sample of potassium-40 will remain after 3.9109 years of radioactive decay?
100 grams
If you have 100 grams of plutonium-239 how many grams of plutonium-239 will remain after 24000 years?
Slightly over 50 grams; the half-life of Pu-239 is around 24110 years, so in 24000 years a little less than half will have decayed to U-235.
Are there any novels about the radium dial painters?
Radium is not used as a component of luminescent paints from about 80 years !
