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.
What total mass of a 16 gram sample of 60co will remain unchanged after 15.8 years?
After 15.8 years, half of the original sample of 60Co would have decayed. This means that 8 grams of the original 16 gram sample will remain unchanged after that time period.
What would cause allele frequencies to remain unchanged?
Only one thing: extinction.
How much cesium would remain from a 10 g sample after 2 years?
5g would remain
Which fraction of an original 20.00-gram sample of nitrogen-16 remains unchanged after 36.0 seconds?
Nitrogen-16 has a half-life of about 7.13 seconds. After 36.0 seconds, there would be 3 half-lives. Therefore, 1/2 * 1/2 * 1/2 = 1/8 of the original sample remains unchanged.
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.
How many unchanges atoms would remain after 3 half lives if the initial sample had 600 unchanged atoms?
After 3 half-lives, half of the original sample would remain unchanged. After the 1st half-life: 300 unchanged atoms. After the 2nd half-life: 150 unchanged atoms. After the 3rd half-life: 75 unchanged atoms would remain.
What total mass of a 16 gram sample of 60co will remain unchanged after 15.8 years?
After 15.8 years, half of the original sample of 60Co would have decayed. This means that 8 grams of the original 16 gram sample will remain unchanged after that time period.
Molybdenum-99 has half a half-life of 66 hours. after 132 hours how much of an initial sample of 10 ci of mo-99 would remain?
After 132 hours, 1/4 of the initial sample of 10 Ci of Mo-99 would remain. Since the half-life is 66 hours, after 66 hours half of the sample would remain (5 Ci), and after another 66 hours (totaling 132 hours), half of that remaining amount would be left.
