Final answer:
To calculate the number of moles of glucose in 5.380 g, divide the mass by the molar mass of glucose (180.16 g/mol), resulting in approximately 0.02987 moles of glucose.
Step-by-step explanation:
The number of moles of glucose (C6H12O6) in 5.380 g of glucose can be calculated by dividing the mass of glucose by its molar mass. The molar mass of glucose is approximately 180.16 g/mol.
To find the number of moles, use the formula:
Number of moles = mass (g) ÷ molar mass (g/mol)
For glucose:
Number of moles = 5.380 g ÷ 180.16 g/mol
The calculation yields:
Number of moles of glucose = 0.02987 moles (rounded to five significant figures)
This value represents the quantity of substance in terms of moles for the given mass of glucose.
