A) \[105.4\]
B) \[118.2\]
C) \[137.2\]
D) \[154.2\]
Correct Answer: D
Solution :
We know that\[m=\frac{1000{{K}_{f}}\times w}{\Delta TW}\] Here, \[\Delta T={{1.2}^{o}}C,\,\,{{K}_{f}}={{1.85}^{o}}\] \[w=5g,\,\,W=50\,\,g\] \[\therefore \] \[m=\frac{1000\times 1.85\times 5}{1.2\times 50}=154.2\]You need to login to perform this action.
