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?
After 90 years, about 0.5 mg of cesium-137 would remain since cesium-137 has a half-life of about 30 years. This means that half of the initial amount would have decayed in 30 years and another half in the next 30 years, leaving around 0.5 mg after 90 years.

Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay.

What would you use to mesure a banana a gram or kilagram?
a gram
List the steps of the gram-staining procedure in order and fill in the color of gram-positive cells and gram-negtive cells after each step?
Apply crystal violet stain - Both gram-positive and gram-negative cells appear purple. Add iodine solution - Both gram-positive and gram-negative cells still appear purple. Rinse with alcohol/acetone - Gram-positive cells remain purple, while gram-negative cells lose the purple color. Counterstain with safranin - Gram-positive cells remain purple, gram-negative cells appear pink/red.
Chaser-381 has a half life of 2 days if you start with 8 grams of chaser-381 how much would you have left after eight days?
Eight days would be four half-lives. One-half to the fourth power is one-sixteenth. So you would have half a gram left.
