Question

If this sugar was all sucrose (C₁₂H₂₂O₁₁), how many moles of sucrose sugar is in 100g of this sports drink?

Answer 1

Here we want to convert the mass of sucrose sugar to moles, so we will need to find the molar mass of sucrose C12H22O11

Molar Mass of C12H22O11 = 12 mol C *12 g/molC + 22 mol H*1 g/molH + 11 mol O *16 g/mol O = 342 g/mol

Now that we have the molar mass we can convert 100 g to moles

100 g * 1 mol C12H22O11 / 342 g = 100 / 342 = 0.29 mol C12H22O11
