Answer:
The mass of sugar used is 427.5 grams.
Explanation:
The formula of common sugar is [tex]\mathrm{C_{12}H_{22}O_{11}}[/tex].
Its molar mass of molecule is 342 grams per mole.
The number of moles of sugar used is equal to '1.25'
[tex]\mathbf{Mole=\frac{Mass \ given \ in \ grams}{Molar \ mass \ of \ molecule \ in \ grams}}[/tex]
[tex]\textrm{Mass in grams}=\textrm{Mole} \times \textrm{Molar mass of molecule in grams}[/tex]
[tex]\textrm{Mass in grams}= 1.25\times342[/tex]
[tex]\mathbf{Mass \ in \ grams=427.5 g}[/tex]
(NOTE : You can calculate molar mass by adding the mass of all the atoms present in the atom.
Mass of Oxygen (O) = 16 ; Total number of Oxygen atoms present = 11
Mass of Hydrogen (H) =1 ; Total number of Hydrogen Atoms present = 22
Mass of Carbon (C) = 12 ; Total number of Carbon atoms present = 12
Total mass of molecule = 12 × 12 + 1 × 22 + 16 × 11 = 342)
