Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.
The average natural abundance of C-13 is listed as 1.109%. Thus, in a 20000-atom sample of carbon there would be (20000)(0.001109) = 22 atoms of C-13
The number of carbon-13 atoms is 130.
Approx. 175 C-13 atoms.
The answer is 6,2729.10e+26 carbon atoms.
Yes they wouldn't have the same composition but not properties!
On average, air contains around 76.7 % nitrogen gas by mass. This means that there is around 0.959 kg of nitrogen present.

10,500 years old The carbon-14 in a wooden sample shows a ratio of 0.0093 between the carbon-14 in the wood and present-day samples. The half-life of carbon-14 is 5,730 years. How old is the wood? 38,700 years old
Carbon-14 dating is the measurement of an object's age by comparing the amount of carbon-14 to the amount of carbon-12 and carbon-13 present in the sample.

in every sample of carbon monoxide ,the mass ratio of carbon to oxygen is 3:4
They are identical.
A 63,60 g sample of carbon is equal to 5,296 moles.
80,0 moles of CO2is equal to 3 520,8 g.

well when the heart pumps then its the sample
Roughly, subtract the atomic number (6) from it's atomic mass (12.01) and round to the nearest integer to get the average number of neutrons in a carbon sample, in this case 6.
