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).
Too high because there will be extra water weight on the silver chloride therefore making it seem like there is more silver than there actually is
Answer:
The correct answer is 0.25 moles/liter
Explanation:
Molarity is a measure of concentration and is defined as the moles of solute in 1 liter of solution.
2 L solution-----0,5 moles of CaO
1 L solution -----x= (1 L solutionx0,5 moles of CaO)/2 L solution =
<em>x=0, 25 moles of Cao ---> 0,25M</em>
2,2,4-trimetilpentano is the answer.
Answer: Kc= 4.653
Explanation:
From The equation of reaction
CO(g)+2H2(g)⇌CH3OH(g)
From the question
[CH3OH] =0.0679 moles
[CO]= 0.160moles
[H2]= 0.302
Kc = [CH3OH]/[CO] [H2]^2
Kc=[0.069]/[0.16]×[0.302]^2
Kc= 4.653
