A) 54
B) 36
C) 18
D) 9
Correct Answer: C
Solution :
\[{{w}_{A}}=xg,\] \[{{m}_{A}}=18,\] \[{{x}_{A}}=1-0.6=0.4\] \[{{w}_{B}}=69g,\]\[{{m}_{B}}=46,\]\[{{x}_{B}}=0.6,\]\[{{x}_{A}}=\frac{{{n}_{A}}}{{{n}_{A}}+{{n}_{B}}}\] \[0.4=\frac{{{w}_{A}}/{{m}_{A}}}{{{w}_{A}}/{{m}_{A}}+{{w}_{_{2}}}/{{m}_{B}}}=\frac{x/18}{\frac{x}{18}+\frac{69}{45}}\] \[x=18\]You need to login to perform this action.
