We have a problem in chemistry class and we are incapable of agreeing on an answer can someone help, please!


To create Champagne, we ferment raisin jus in a closed bottle to create bubbly wine. the réaction transforms the sugar (C6H12O6) into ethanol (C2H5OH) and into carbon dioxide with the following formula:


C6H12O6 --> 2 C2H5OH + 2 CO2


We ferment 750 mL of raisin jus in a 900 mL bottle until 15% of the initial mass of raisin jus transforms into ethanol. Knowing that the volumic mass of raisin jus is 1,0g/mL and that the one of ethanol is 0.79 g/mL, what will be the pressure of the carbon dioxide in the bottle if the temperature is of 25 C? Suppose that the carbone dioxide does not dissolve in water.


Thank you! Know that we mostly use the formula PV=nRT so that is needed  thank you for all help
