Would 500000 micrograms be equal to 0.5 grams?
Yes, that is true. This is because there are 1,000,000 micrograms in a gram. So 0.5 grams is 500,000 micrograms.
A radioactive element has a half-life of 3000 years. If a sample of this element begins with a mass of 60 grams how long would you have to wait for the mass to decrease to 15 grams?
You would have to wait 6,000 years for this to occur, because it requires twice the half-life to reduce the radioactive isotope to 1/4 of its original mass.
What are the steps required to find the mass of an element from a given amount of the element in moles?
The mass of 1 mole of the element is used as conversion factor to covert grams to moles. ~APEX
Is relative humidity given in percent or grams?
Grams
How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
What is the rarest element on earth?
The rarest naturally occurring element on Earth is astatine. It is a radioactive element with a very short half-life, making it extremely rare and difficult to study. It is estimated that there is only a few grams of astatine present in the Earth's crust at any given time.
How many grams are in 500000 kilograms?
500000000 grams
How many grams are in 500000 kg?
1,000,000
What element in group 7 is so rare that there is only a few grams of it on earth?
Astatine (At) is the element in group 7 that is so rare that there are only a few grams of it on Earth. It is a radioactive element and is created through the decay of heavier elements.
A 2.5 gram sample of a radioactive element was formed in a 1960 explosion of an atomic bomb at Johnson Island in the Pacific Test Site The half-life of the radioactive element is 28 years How much?
After 28 years, half of the 2.5 grams (1.25 grams) would remain. After another 28 years (56 years total), only 0.625 grams would remain, and so on. The amount of the radioactive element left can be calculated using the formula: remaining amount = initial amount * (1/2)^(years/half-life), where the initial amount is 2.5 grams and the years is the given time.
Would 500000 micrograms be equal to 0.5 grams?
Yes, that is true. This is because there are 1,000,000 micrograms in a gram. So 0.5 grams is 500,000 micrograms.
What does 500 grams equals?
500000 mgs 0.5kg
A radioactive element has a half-life of 3000 years. If a sample of this element begins with a mass of 60 grams how long would you have to wait for the mass to decrease to 15 grams?
You would have to wait 6,000 years for this to occur, because it requires twice the half-life to reduce the radioactive isotope to 1/4 of its original mass.
How do you find the moles of a given element?
One takes the atomic mass of that element (the number under the element on a periodic table, measured in amu). That number is the number of grams of the element it takes to make one mole. in other words:X grams (of element)(Atomic Mass of element)= --------------1 mol (of element)
A radioactive element has a half-life of 1000 years. If a sample of this element begins with a mass of 20 grams how long would you have to wait for the mass to decrease to 5 grams?
Since the element has a half-life of 1000 years, it will take two half-lives for the mass to decrease to 5 grams from 20 grams. Two half-lives equal 2000 years, so you would have to wait 2000 years for the mass to decrease to 5 grams.
A radioactive element has a half-life of 2000 years. If a sample of this element begins with a mass of 100 grams how long would you have to wait for the mass to decrease to 25 grams?
You would have to wait 6,000 years for this to occur, because it requires twice the half-life to reduce the radioactive isotope to 1/4 of its original mass.
How long would you have to wait for the mass to decrease to 25 grams if a radioactive element has a half-life of 2000 years and the sample of the element begins with a mass of 100 grams?
You would have to wait for 2000 years for the mass to decrease to 50 grams (one half-life) and another 2000 years to decrease to 25 grams (two half-lives). So, in total, you would have to wait 4000 years for the mass to decrease to 25 grams.
