A) 3.0
B) 3.5
C) 5.0
D) 6.5
Correct Answer: C
Solution :
Given vapour density = 70 \[\therefore \] molecular weight \[=2\,\,\times \]vapour density \[=2\times 70=140\] \[{{[CO]}_{x}}={{(12+16)}_{x}}={{(28)}_{x}}\] \[\because \] \[{{(28)}_{x}}=140\] \[x=\frac{140}{28}=5\] \[\therefore \] Formula is \[{{(CO)}_{5}}\]You need to login to perform this action.
