CxHy + O2 --> x CO2 + y/2 H2O
Find the moles of CO2 : 18.9g / 44 g/mol = .430 mol CO2 = .430 mol of C in compound
Find the moles of H2O: 5.79g / 18 g/mol = .322 mol H2O = .166 mol of H in compound
Find the mass of C and H in the compound:
.430mol x 12 = 5.16 g C
.166mol x 1g = .166g H
When you add these up they indicate a mass of 5.33 g for the compound, not 5.80g as you stated in the problem.
Therefore it is likely that either the mass of the CO2 or the mass of H20 produced is incorrect (most likely a typo).
In any event, to find the formula, you would take the moles of C and H and convert to a whole number ratio (this is usually done by dividing both of them by the smaller value).
Answer:Carbohydrates improve athletic performance by delaying fatigue and allowing an athlete to compete at higher levels for longer.
Explanation:
The new volume of the bottle is 5.07 L.
<h3>What is Boyle's Law?</h3>
It is a gas law that states the pressure decrease with the increase in the pressure.
By the formula

Given that, volume1 is 2.3l
Pressure1 is 4 atm.
Pressure2 to 0.65 atm.
V2 is to find?
Putting the values in the equation

Thus, the new volume of the bottle is 5.07 L.
