When you divide the mass of a substance by its volume you get its what?
You get its density. Density is a measure of how much mass is contained within a specific volume of a substance.
What is another way to say much space a substance takes up?
Another way to say how much space a substance takes up is to refer to its volume. Volume describes the amount of three-dimensional space an object or substance occupies.
To measure how much stuff is in a specified volume of a substance seciemtists scientists use?
Scientists use the concept of density to measure how much stuff (mass) is in a specified volume of a substance. Density is calculated by dividing the mass of the substance by its volume. This provides a measure of how tightly packed the particles are within the substance.
How much stuff is in a specified volume of a substance scientists use?
Scientists use the concept of density to determine how much stuff (mass) is contained within a specified volume of a substance. Density is calculated by dividing the mass of a substance by its volume, so the amount of stuff in a specified volume depends on the density of the substance.
What is the half-life of a substance?
Half-life refers to a property of radioactive materials. The half life in the length of time it takes half of the quantity of an element to decay and become a more stable, non radioactive element. So if a 1 kg block of a substance had a half life of 10,000 years, in 10,000 years time there would 0.5 Kg of radioactive material remaining in the block. 10,000 years later there would again only be half as much, so there would then be 0.25 Kg of the radioactive material. Every further 10,000 years the quantity of the remaining radioactive material would half.
You took percocet on Friday will it show on monday?
depends on how much, but opiates halflife is anywhere from 12 to 72 hours. drink alot of water in the next couple of days and you should be safe
If Uranium has a halflife of 1 day how much is left at the end of the third day?
The half life of uranium is not one day. For an isotope with the half life or one day, after 3 days: the quantity remained is 12,5 %.
30 gram of a radioactive substance that has a half-life of 2 days after 2 days how much will be left?
With radioactive decay, predicting when any individual atom will decay is nearly impossible. However, when a lot a particles are present, then it is possible to get a general idea of how much will decay in a certain period of time. The half-life is this measurement, and it is the time that it takes for one halfof the substance to decay. Hence half-life or how long it takes for half to "die".For any size sample of a substance, the half-life is how long it takes for half to be left, so for a substance with a half-life of 2 days, half of the substance will decay in two days. Therefore your answer is simply half of 30g which is 15g.Additional reading: http://simple.wikipedia.org/wiki/Radioactive_decay
A radioactive substance has has life of 5 days initial mass of 12kg how much the original isotope will remain after 10 days?
After 10 days, 1/2 of the original isotope will remain since its half-life is 5 days. This means 6kg of the original isotope will remain after 1 half-life, which remains the same after 10 days since another half-life has passed.
Why is density a characteristic of a substance and volume and mass are not?
The volume and mass of a substance are independent of the substance itself, but depend upon how much there is of the substance The density of a substance is the relation between how much volume you have of a substance and how much mass that volume has (and vice-versa). It is independent of how much there is of the substance and is thus a characteristic of the substance.
A particular element has a half-life of 27 days After 54 days have elapsed how much of the radioactive material is left?
1/4. After 27 days, half of the material will have decayed. After another 27 days half of the remaining material will have decayed. Half of half is 1/4.
How much of an 80-milligram sample of Iodine-131 would be left after 32 days?
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.
What is the equation to calculate the percentage of each substance in a mixture?
(percentage)x(how much of the substance)+(percentage)x(how much of the substance)=(total percentage)(total of substance)
How much mass does Kia's remaining water have?
The remaining water in Kia's bottle has a mass of about 500 grams.
What is the half life of uranium 238 if 85.719 percent of any given amount remains after 1 billion years?
The halflife of 235U is 704 million years. 1420 million years is approximately two halflives, so about 24.7% would be remaining.
How many milliliters in 650 milligrams?

How many milligrams of an initial 63 of calcium-47 remain after 27?
To determine how much calcium-47 remains after 27 days, we need to know its half-life, which is about 4.5 days. After 27 days, which is approximately 6 half-lives, the amount remaining can be calculated using the formula: ( \text{remaining} = \text{initial} \times \left( \frac{1}{2} \right)^{\text{number of half-lives}} ). Therefore, starting with 63 mg, the calculation would be ( 63 \times \left( \frac{1}{2} \right)^6 ), resulting in approximately 0.98 mg remaining.
