The volume of a gas can be found by using ideal gas formula. The formula would be:
V= nRT/P
where
n= number of the molecule (mol)
R= constant
T= temperature
P= pressure
Then, the answer would be
<span>1. temperature
2. pressure
3. mass
4. number of molecules </span>
1.98 × 10^<span>-11</span><span> J i just took it this is the right awnser</span>
The Half life is the time taken for a radioisotope or a radioactive substance to decay by half its original amount. The half life of carbon 14 is 5600 years.
Original mass is 100%
Remaining amount is 24%
Therefore; 0.24 = 1 × (1/2)^n
n = log 0.24/log 0.5
= 2.06
therefore, the age of the fossil is 5600×2.06
= 11529.8
≈ 11529 years
