If you had a 100 gram sample of plutonium how much would remain in 43 years?
Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay. In 43 years, which is much shorter than the half-life, only a tiny fraction of the plutonium would decay. Therefore, after 43 years, approximately 99.83 grams of the original 100-gram sample would remain.
Would a penny weigh a gram or kilogram?
gram
Would a dime weigh about a kilogram or a gram?
one gram roughly
How would you write 1 gram as a decimal?
One (1) gram as a desimal would be written as "1.0 grams."
Would you use gram or kilogram to measure the unit of a nickel?
it would be a gram and if you didn't know a kilogram is equal to 1,000 grams
How much would still remain in 30 minutes if you had a 5 - grm sample of lawrencium?
Lawrencium has a half-life of about 215 minutes. After 30 minutes, about 85% of the original sample would remain. Therefore, approximately 4.25 grams of lawrencium would still be present in a 5-gram sample after 30 minutes.
What would happen if you forgot to counterstain with safranin?
Gram neg cells would remain clear
How many grams of radium-222 remain in a 12-gram sample after 76 seconds?
After 76 seconds, half of the radium-222 would have decayed (its half-life is about 3.8 days). Therefore, the quantity of radium-222 remaining in the 12-gram sample would be 6 grams.
How much does lawrencium cost in grams?
The cost of lawrencium is not readily available as it is a synthetic element that is produced in very small quantities and primarily used for research purposes. It is not typically sold in gram quantities due to its scarcity and high cost of production.
What is the weight of one gram of mineral oil?
One gram of mineral oil has a weight of one gram, as weight is a measure of the force of gravity acting on an object. The weight would remain the same regardless of the substance.
How much of a 100 gram sample would remain unchanged after two hours?
This would depend on the specific sample and its stability. Without additional information, it is not possible to determine how much of the sample would remain unchanged after two hours.
Radioactive iodine-131 has a half-life of eight days. The amount of a 200.0 gram sample left after 32 days would be -?
12.5 g
If 1.0 mg of cesium-137 decays over a period of 90 years how many mg of cesium-137 would remain?
Since the half-life of cesium-137 is about 30 years, 3 half-lives would have passed in 90 years. The first half-life would leave .5 mg of cesium-137. The second would leave .25 mg, and the third half-life would leave .175 mg of cesium-137.
If you had a 100 gram sample of plutonium how much would remain in 43 years?
Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay. In 43 years, which is much shorter than the half-life, only a tiny fraction of the plutonium would decay. Therefore, after 43 years, approximately 99.83 grams of the original 100-gram sample would remain.
How much of a 100 gram sample would remain unchanged after 2 hours?
To determine how much of a 100 gram sample would remain unchanged after 2 hours, it is necessary to know the specific decay rate or change process of the sample. For example, if the sample undergoes a decay process with a known half-life, you can calculate the remaining amount using the formula for exponential decay. Without this information, it's impossible to provide an exact answer. In general, if no decay occurs, the entire 100 grams would remain unchanged.
What would you use to mesure a banana a gram or kilagram?
a gram
What is the length of gram seedling after 10 days and after 20 days?
The length of gram seedlings can vary based on factors such as environmental conditions, soil quality, and specific gram variety. Generally, after 10 days, gram seedlings may reach about 5-15 cm in height. After 20 days, they can grow to approximately 15-30 cm. For precise measurements, it’s best to refer to specific growth studies or agricultural guidelines related to the gram variety being cultivated.
