Calculate the boiling point (in oC) of a calcium nitrate (Ca(NO3)2; 164.1g/mol) solution with a concentration of 1.45 molarity. The solution has a density of 1.12 g/mL. Water has a boiling point elevation constant of 0.512 oC/m. (assume 1 atm total external pressure & idea behavior)
my answer 101.8432
please explain and tell me where is my mistake
Homework Answers
FOR IONIC SOLID VAN'T HAFF FACTOR (i) IS USED.
SINCE NON IONIC SOLID LIKE SUCROSE DO NOT GET DISSOCIATED FOR THEM i EQUAL TO 1.
AND ONE THING ALSO, I THINK YOU MADE MISTAKE IN WRITING CONCENTRATION IN MOLARITY INSTEAD OF MOLALITY.
SINCE ELEVATION IN BOILING POINT IS COLLIGATIVE PROPERTY MOLALITY SHOULD BE USED.
IF IT'S REALLY IN MOLARITY THEN CONVERT IT INTO MOLALITY AND THEN CALCULATE.
CONFIRM ME IF GOT THE ANSWER CORRECT OR NOT.
