Question

1M glucose solution has a freezing point of -1.86°c. If 10ml of 1M Glucose is mixed with 30 ml of 3M glucose then the resultant solution have freezing point ofa) -2.79 °cb) -4.65°cc) -6.36°cd) -744°c​

Answer 1

Answer:

7.44°c

Explanation:

as 1M glucose =10ml

therefore 3M = 30 ml

therefore total M = 4M

as 1M = 1.86°c

4M = (?)

therefore freezing point = 1.86×4

= 7.44°c
