Glucose At Room Temperature
need help on finding the mole of the substance after reaction?
Propane gas, C3H8, reacts with oxygen to produce water and carbon dioxide. Propane has a density of 2.02 at room temperature.
C3H8(g)+5O2(g)—->3CO2(g)+4H2O(l) propane
Part A
How many moles of water form when 5.30 L propane gas (C3H8) completely react?
= moles
Part B
How many grams of CO2 are produced from 18.9 g oxygen gas and excess propane?
=g
Part C
How many grams of H2O can be produced from the reaction of 8.90×1022 molecules propane gas, C3H8?
=g
At a winery, glucose () in grapes undergoes fermentation to produce ethanol (C2H6O) and carbon dioxide.
C6H12O6—-> 2C2H6O+2CO2
glucose ethanol
Part A
How many moles of glucose are required to form 121 g of ethanol?
= moles
Part B
How many grams of ethanol would be formed from the reaction of 0.250 kg of glucose?
=grams
In order to give an answer to your question it is necesary to convert 5.30 litres C3H8 to grams and then moles. You gave a density of C3H8 as 2.02. What are the units of this density: I have checked my references and I find that the density of propane is 1.83 kg/m3, at room temp. I do not want to do all the work for nothing – where did you get your value for density, and critically for all questions, what are the units.
If you can provide this data, your question will be answered.
