Calculate the molar solubility of copper(ii) arsenate (cu3(aso4)2) in water. use 7.6 x 10^-36 as the solubility product constant of cu3(aso4)2.
9.1 x 10^-4 m
3.4 x 10^-2 m
3.7 x 10^-8 m
8.7 x 10^-2 m

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)]
