What is 5 percent of 1500 dollars?
Well...if you drop a 0 for ten percent that would be 150. So half of that would be 5 percent which is 75.
What is half of one half of a percent?
It is a quarter of a percent
What is one half of one percent of 80000?
One percent of 80, 000 would be 8000. One half of 8000 is 4000. Therefore, the correct answer of this question is 4ooo.
What is 1 percent of 50 million?
well 2 percent of 50 million would be 1 million so 1 percent would be half of that: 500 000
How do you write one and a half percent?
1.5%one and a half percent = 11/2% or 1.5%
What percent of carbon14 is left after 5 half-lives?
3.125% would be left over.
A sample of a radioactive element has a mass of 80 g. How much parent and daughter materials are in the sample after two half-lives?
A half-life is the amount of time it takes for half of the material to decay. So if you started with 80g After 1 half-life you would have 40 g After 2 half-lives you would have 20 g After three half-lives you would have 10 g
Which statement is true about half-lives a Different atoms of the same element have different half-lives. b Each radioactive isotope has its own half-life. c All radioactive nuclides of an element?
The correct answer is: Half-lives are not affected by temperature.
How long it would take for 99.9 percent of Cs to decay if its half-life is 30 years?
10 half-lives or 300 years.
What is the half-life of every radioactive element?
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
How much cesium is left after 4 half-lives?
1/16 of the original sample of any unstable element remains after 4 half lives.
How can half lives be shortened?
Half life of an element can't be changed.. It is a characteristic of a radioactive element which is independent of chemical and physical conditions.. Half life is that time in which half of radioactive sample( i.e., a radioactive element) decomposes. So no matter what amount you take half life of an element remains same.
What percent of potassium-40 remains after two half-lives?
25%
After three half-lives what percent of the radioactive isotope is remaining?
12.5% is remaining.
How many half-lives have passed for 50 percent of the original radioactive material?
One half-life.
How many half-lives have passed?
To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.
An element has 2 naturally occuring isotopesIsotopes 1 has a mass of 106.905 amu and a relative abundance of 51.8 percent and Isotopes 2 has a mass of 108.904 amu and abundance of 48.2 percent Find th?
