In 1951, fragments of charcoal from the excavation of the cave were analyzed. The charcoal sample had a specific activity of 2.34 d/min*g. In 2002, a new radiocarbon analysis on a reindeer antler baton was performed. The antler sample had a specific activity of 1.56 d/min*g. The ratio of 12C/14C for living organisms results in a specific activity of 15.3 d/min*g. The half-life for 14C is ~5730 years. Calculate the age that was determined for both the 1951 and the 2002 analysis. Please show your work.

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

explanation:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

did anyone actually do this? like if anyone has submitted this i rly need .
