A. The molar mass of sucrose can be calculated by adding up the atomic masses of all the atoms in one molecule of sucrose:
Molar mass of sucrose = 12(atomic mass of C) + 22(atomic mass of H) + 11(atomic mass of O)
= 12(12.011) + 22(1.008) + 11(15.999)
= 342.296 g/mol
Therefore, the molar mass of sucrose is 342.296 g/mol.
B. The number of moles of sucrose can be calculated using the formula:
moles = mass / molar mass
Substituting the given values into the formula:
moles = 1.202 g / 342.296 g/mol
= 0.00351 mol
Therefore, there are 0.00351 moles of sucrose in the sample.
A sample of table sugar (sucrose, C12H22O11) has a mass of 1.202 g.
A. Calculate the molar mass of sucrose.
B. Calculate the number of moles of sucrose contained in the sample. Show work.
