Use the table of molar masses to complete the question. Do NOT use any other values except the ones provided in the table below. Element Molar Mass (g/mol) carbon 12.01 hydrogen 1.01 oxygen 16.00 A chemist will use a sample of 30g of glucose ( C6H12O6 ) in an experiment. Determine the number of moles of glucose the chemist will use based on the molar mass values provided in the table. (Your value should be rounded to 2 decimal places; i.e. the hundredths place). (2 points) The number of moles the chemist will use is: moles.
To determine the molar mass of glucose (C6H12O6), we need to calculate the total molar mass by adding up the molar masses of each element present in the compound:
6 carbon atoms: 6 x 12.01 g/mol = 72.06 g/mol
12 hydrogen atoms: 12 x 1.01 g/mol = 12.12 g/mol
6 oxygen atoms: 6 x 16.00 g/mol = 96.00 g/mol
Total molar mass of glucose (C6H12O6) = 72.06 g/mol + 12.12 g/mol + 96.00 g/mol = 180.18 g/mol
Now, we can calculate the number of moles in 30g of glucose:
Number of moles = Mass / Molar mass
Number of moles = 30g / 180.18 g/mol
Number of moles ≈ 0.17 moles
Therefore, the chemist will use approximately 0.17 moles of glucose in the experiment.
