What is the formula to calculate the remaining mass of an isotope with a half life of 27 seconds after 24 hours?

The equation for half-life is ...
AT = A0 2(-T/H)
... where A0 is the starting activity, AT is the ending activity at some time T, and H is the half-life in units of T.
Given that A0 is 1, H is 27 seconds, and T is 86400 seconds (one day, or 24 hours), AT is simply 5.06x10-964.
This sounds a bit extreme, and perhaps the question was mis-stated, but that's what the equation produces.

Is lithium 8 an isotope why?
Yes, but it has a halflife of only 0.86 seconds.
What is the decay of neon-23 by beta emission?
In order to have an equation, we need to know what isotope of neon we are dealing with. Neon 2 is not an isotope.
The half-life of fluorine-20 is 114 seconds After 14 seconds how much of the original amount of fluorine-20 will remain?
THE QUESTION IS INVALID. THE HALF-LIFE OF FLUORINE-20 is 11.07 SECONDS. There will be about 0.92 of of an isotope with a half-life of 114 seconds remaining after 14 seconds. The equation for half-life decay is AT = A0 2(-T/H) where T is time and H is half-life. 2(-14/114) is equal to about 0.92. In the case of fluorine-20, 2(-14/11.07) is about 0.42.
How long did element 112 stay stable for?
The most stable isotope is 285Cn, which has a half life of 30 seconds. The least stable isotope is 277Cn, which has a half life of 0.7 milliseconds.
How to calculate the speed of the wind in anemometer?
If you count the number of times it spins in 60 seconds, you find out each rotation is .1mph. So for example it spins 65 times in 60 seconds you can calculate the wind speed in 6.5mph.
Isotope A has half-life of seconds and isotope B has a half-life of millions of years which isotope is more radioactive?
Isotope A
How do you calculate seconds when given meters per second?
You can't convert between seconds, and meters/second. If you have a problem that involves speeds, use the formula: distance = speed x time.
Is lithium 8 an isotope why?
Yes, but it has a halflife of only 0.86 seconds.
How do you calculate mph from seconds?
MPH = miles per hour. In order to calculate hours from seconds, you just need to know that there are 3,600 seconds in an hour.
What is the decay of neon-23 by beta emission?
In order to have an equation, we need to know what isotope of neon we are dealing with. Neon 2 is not an isotope.
4 Calculate the current if four coulombs of charge pass a point in a wire every two seconds Show the formula calculations and the units?
(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.
What is the formula for converting seconds into hours?

What is the formula to convert hours to seconds?
hours x 3,600 = seconds
How do you calculate the amount of seconds in a day?
Multiply by 24x60x60. This is 86400 seconds in a day.
