A) \[352\]
B) \[253\]
C) \[275\]
D) \[310\]
Correct Answer: B
Solution :
\[{{w}_{1}}=100g,\] \[{{w}_{2}}=10g,\] \[\Delta {{T}_{b}}={{1}^{o}},\,{{K}_{b}}=2.53\,K{{m}^{-1}}\] \[{{M}_{2}}=\frac{1000{{K}_{b}}\times {{w}_{2}}}{{{w}_{1}}\times \Delta {{T}_{b}}}\] \[=\frac{1000\times 2.53\times 10}{100\times 1}\]You need to login to perform this action.
