Answer:
1,7Kg of is produced
Explanation:
<em>Balanced chemical reaction</em>
To find the mass of produced in a reaction, we need to start by identifying that chemical reaction and balancing it.
The question give us the reactants and the products, do we know:
+ ⇒ +
Counting C, H and O in reactants and products; and balancing them with stoichiometric coefficients, we have that the balanced chemical equation is:
2 + 160 ⇒ 114 + 110
<em>Stoichiometry</em>
The question says us that 1.2 Kg of fat () react.
To find the amount of we need to find the moles of . The way to do it, is using the molar mass:
Taking the molar mass of each element in the periodic table, multiplying by the subscript and adding all the partial values:
The moles of that react are:
The balanced chemical reaction tell us that each 2 moles of that react, produce 110 moles of . It means that:
1.6826 mol mol
Finally, using the molar mass of , we can find its mass:
92.543 mol =1665.7 g
With two sig figs, the mass:
1665.7g ≅ 1.7 Kg
