When 52.4 g of a compound was burned in a bomb calorimeter that contained 0.256 kg of water the temperature rise of the water in the calorimeter was 50.0C. If the heat of combustion of the compound is 1,651 kJ/mol, what is the molar mass of the compound? Specific heat of water is 4.184 J/g. Answer to 0 decimal places and
enter the units

Determine the empirical formula of a compound containing 40.6 grams of carbon, 5.1 grams of hydrogen, and 54.2 grams of oxygen. in an experiment, the molar mass of the compound was determined to be 118.084 g/mol. what is the molecular formula of the compound? for both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?
