An experiment requires 100 \[c{{m}^{3}}\] of \[20.0%,\]\[{{H}_{2}}S{{O}_{4}}\], density \[1.14g/c{{m}^{3}}\]. How much concentrated acid of density \[1.84g/c{{m}^{3}}\] and containing \[98%\] \[{{H}_{2}}S{{O}_{4}}\] by weight, must be diluted with water to prepare \[100\text{ }c{{m}^{3}}\] acid of the required solution?

A)  \[8.1\,\,c{{m}^{3}}\]       

B)  \[12.7\,\,c{{m}^{3}}\]  

C)  \[18.1\,\,c{{m}^{3}}\]      

D)  \[21.3\,\,c{{m}^{3}}\]
