Why can't scientists simply use carbon-12 (12C) do determine the age of dead carbon-based life forms?

carbon-12 is not radioactive

Explanation:

The measurement of the age of dead carbon based life forms requires the use of a radioactive isotope hence it is often referred to as radiocarbon dating.

Carbon-12 and Carbon-14 occur together in living things.The half life of Carbon-14 is about 5670 years.

Hence, since Carbon-12 is not radioactive, it can not be used to measure the age of dead carbon based materials.

answer: mercury

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
