Sample of glucose contains 1.270x10^21 carbon atoms. What is the mass of this sample in grams

Answer 1

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.
