Acalorimeter contains 280.0g of water at 13.5c. when 0.250g of a substance with a molar mass of 510.0g/mol is dissolved, the temperature of the resultant solution increases to 17.5c. assume that the specific heat and density of the resulting solution are equal to those of water, 4.18j/gc and 1.00 g/ml, respectively and assume that no heat is lost to the calorimeter itself, nor to the surroundings. calculate the amount of heat in joules released by dissolving the substance.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration. ï‚· fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) ï‚· record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. ï‚· record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
