Sample of Glucose, C6H12O6 contains 1.270x10^21 carbon atoms. How many atoms of hydrogen does it contain
Glucose has the chemical formula C6H12O6. This means that for every molecule of glucose, there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
Given that there are 1.270x10^21 carbon atoms in the sample of glucose, we can calculate the number of hydrogen atoms by using the ratio of carbon atoms to hydrogen atoms in the molecule.
1 molecule of glucose has 12 hydrogen atoms and 6 carbon atoms.
So, 1 molecule of glucose contains 12/6 = 2 times more hydrogen atoms than carbon atoms.
Therefore, the sample of glucose containing 1.270x10^21 carbon atoms will have 1.270x10^21 x 2 = 2.54x10^21 hydrogen atoms.
