The heat required to raise the temperature of the cup from 25 c to 50 c is calculated as follows
Q (heat) = c x delta T
c = specific heat capacity = 0. 820 j/c
delta T = change in temperature ( 50 c- 25 c = 25c
= 0.820 j /c x 25 c = 20.5 j

Answer:
Osmolarity of solution of KCI = 0.40 osmol
Explanation:
Given:
KCL ⇒ K⁺ + Cl⁻
Find:
Osmolarity of solution of KCI
When M = 0.20 M
Computation:
1 mole of KCL = 2 osmol
1 M of KCl = 2 Osmolarity
So,
Osmolarity of solution of KCI = 2 × 0.20
Osmolarity of solution of KCI = 0.40 osmol
