How many grams of ethanol in 1 mole
Web11 feb. 2008 · I remember that I have to do a balanced chemical equation, but seeing as I don't know the chemical formula for citric acid I can't do that. I know that I had to add 0.005 mol of NaOH to the solution. (0.05 L * 0.10 mol/L NaOH). Also if 4 g crystals/100 mL of juice solution, then in 10 mL of the juice solution there would be 0.4 g of crystals. WebIts heat capacity is approximately 24.5 joules per gram-degree Celsius (J/g°C), which is slightly higher than that of water (4.18 J/g°C). This means that it takes more heat to raise the temperature of ethanol by a given amount than it does to raise the temperature of water by the same amount. The heat capacity of ethanol is also dependent on ...
