How many moles of molecules are contained in 25.4g of glucose (C_6 H_12 O_6)

1 answer

To calculate the number of moles of molecules in 25.4 g of glucose (C6H12O6), we need to first calculate its molar mass.

Molar mass of glucose (C6H12O6) = (6 x 12.01 g/mol) + (12 x 1.01 g/mol) + (6 x 16.00 g/mol) = 180.18 g/mol

Now, we can use the formula:

Number of moles = given mass / molar mass

Number of moles of glucose = 25.4 g / 180.18 g/mol = 0.141 mol

Therefore, there are 0.141 moles of glucose molecules in 25.4 g of glucose.
