There are at least two ways to look at this.

Method One :
  The Zn in Zinc Cyanide belongs to valency two while the CN radical
    belongs to valency one.   As a result, you would need two CN radicals
    to bond with the Zn to make it a stable compound.  Hence the formula
    being   Zn(CN)₂

Method Two  :
   
Since the mole of zinc is 4.7 mol and that of CN is 9.5  mol then that
     means that there is twice as much moles of CN as there is Zinc  
     4.7 mol ×  2  =  9. 4 mol
.   Thus the formula would be Zn(CN)₂

Plete the following problems significant figures: 6 × 0.30<br>​
jeka57 [31]
6= Only the digits 1 and 6 are the actual measured values. Therefore we have only 2 significant figures.

0.3= Zeros used as placeholders are not significant. Zeros that come before non-zero integers are never significant. Example 5: The zeros in 098, 0.3, and 0.000000000389 are not significant because they are all in front of non-zero integers. c. If the zeros come after non-zero integers and are followed by a decimal point, the zeros are significant.
