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, \[\Delta T=1.2{{\,}^{o}}C,{{K}_{f}}={{1.85}^{o}}\] \[w=5g,W=50g\] \[\therefore \] \[m=\frac{1000\times 1.85}{1.2\times 50}=154.2\]You need to login to perform this action.
