The mass of ethanol (alcohol) = 538.016 g
<h3>Further explanation</h3>
Given
Reaction
C₁₂H₂₂O₁₁(aq)+H₂O(I) = CH₃CH₂OH(aq)+CO₂(g)
1 kg of sugar = 1000 g
Required
The mass of ethanol
Solution
Balanced equation
C₁₂H₂₂O₁₁(aq)+H₂O(I) = 4CH₃CH₂OH(aq)+4CO₂(g)
mol of sugar (MW = 12.12+22.1+11.16=342 g/mol) :
mol = mass : MW
mol = 1000 g : 342 g/mol
mol = 2.924
From the equation, mol ratio of C₁₂H₂₂O₁₁ : CH₃CH₂OH = 1 : 4, so mol ethanol =
= 4 x mol sugar
= 4 x 2.924
= 11.696
Mass of ethanol(MW=46 g/mol) :
mass = mol x MW
mass = 11.696 x 46
mass = 538.016 g
Because of the ammount of water and the boling point of the Ganga River has changed due to the mixtures of different kind of chemicals and acids
The list which represents the

<h3>Skeleton</h3>
The human skeleton is defined as the internal framework of the human body. It is made up of 206 bones at adulthood stage and the bone mass in the skeleton makes up about 14%
The skeleton is divided into 2 parts:
- The axial skeleton: The axial skeleton is the central unit, consisting of the skull, vertebrae, ribs.
- The appendicular skeleton: It comprise the bones of the extremities
