A0.1014 g sample of a purified cho compound was burned in a combustion apparatus and produced 0.1486 g co2 and 0.0609 g of h2o. what is the empirical formula of this cho compound? enter as c#h#o#, e. g. c2h3o2

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
