Answer:
102g
Explanation:
To find the mass of ethanol formed, we first need to ensure that we have a balanced chemical equation. A balanced chemical equation is where the number of atoms of each element is the same on both sides of the equation (reactants and products). This is useful as only when a chemical equation is balanced, we can understand the relationship of the amount (moles) of reactant and products, or to put it simply, their relationship with one another.
In this case, the given equation is already balanced.
[tex]\tex{C_6H_{12}O_6} \longrightarrow 2 \ C_2H_6O + 2 \ CO_2[/tex]
From the equation, the amount of ethanol produced is twice the amount of yeast present, or the same amount of carbon dioxide produced. Do note that amount refers to the number of moles here.
Mole= Mass ÷Mr
Mass= Mole ×Mr
Method 1: using the mass of glucose
Mr of glucose
= 6(12) +12(1) +6(16)
= 180
Moles of glucose reacted
= 200 ÷180
= [tex]\frac{10}{9}[/tex] mol
Amount of ethanol formed: moles of glucose reacted= 2: 1
Amount of ethanol
= [tex]2(\frac{10}{9} )[/tex]
= [tex]\frac{20}{9}[/tex] mol
Mass of ethanol
= [tex]\frac{20}{9} \times[2(12)+6+16][/tex]
= [tex]\frac{20}{9}(46)[/tex]
= 102 g (3 s.f.)
Method 2: using mass of carbon dioxide produced
Mole of carbon dioxide produced
= 97.7 ÷[12 +2(16)]
= 97.7 ÷44
= [tex]\frac{977}{440}[/tex] mol
Moles of ethanol: moles of carbon dioxide= 1: 1
Moles of ethanol formed= [tex]\frac{977}{440}[/tex] mol
Mass of ethanol formed
= [tex]\frac{977}{440} \times[2(12)+6+16][/tex]
= 102 g (3 s.f.)
Thus, 102 g of ethanol are formed.
