How many moles of oxygen gas are produced from the decomposition of six moles of potassium

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
