A chemist will use a sample of 30g of glucose (C. H1206) 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).
The molar mass of glucose (C6H12O6) can be calculated by adding the molar masses of each element present in the molecule:
6(atomic mass of C) + 12(atomic mass of H) + 6(atomic mass of O)
= 6(12.01 g/mol) + 12(1.01 g/mol) + 6(16.00 g/mol)
= 72.06 g/mol + 12.12 g/mol + 96.00 g/mol
= 180.18 g/mol
Next, we can calculate the number of moles in 30g of glucose by dividing the mass by the molar mass:
30g / 180.18 g/mol ≈ 0.17 moles
Therefore, the chemist will use approximately 0.17 moles of glucose in the experiment.
