Tajriba natijalarini yozish va hisoblashni quyidagi tartibda olib boring:
Kalorimеtrdagi suvning massasi --------------m Olingan tuzning massasi -------------------------mтуз Haroratlar farqi----------------------------------- t t20 - t10 Tuzning nisbiy molеkulyar massasi-----------Мr(tuz) Tuzning erish issiqligi quyidagi formula bilan aniqlanadi: bu еrda Qe.i - tuzning erish issiqligi; С - eritmaning solishtirma issiqlik sig’imi, u 4,18 kj/g-grad. Tuzning erish issiqligini nazariy qiymatini 1-jadvaldan olib, tajribada qilingan absolyut ∆Q va nisbiy d∆ xatolarni quyidagi formulalar yordamida hisoblang: . 1-jadval
