Sample of glucose contains 1.270x10^21 carbon atoms. What is the mass of this sample in grams
To find the mass of the sample, we need to first determine the molar mass of glucose (C6H12O6).
The molar mass of glucose is:
6(C) + 12(H) + 6(O) = 180.16 g/mol
Now, we need to calculate the number of moles of carbon atoms in the sample:
1.270x10^21 atoms / 6 = 2.11667x10^20 moles
Finally, we can calculate the mass of the sample:
2.11667x10^20 moles x 180.16 g/mol = 3.810x10^22 grams
Therefore, the mass of the sample of glucose containing 1.270x10^21 carbon atoms is 3.810x10^22 grams.
