Question

calculate the number of molecules present in 156 gram of benzene c6h6​

Answer 1

Answer:

156/72+6

156/78

=2

that is the ans

Answer 2

Answer:

Explanation:

Formula being used:

No of molecules in C6H6= no of moles of C6H6 * Avogadro number

No of molecules in C6H6= given mass/molar mass * avogadro number

putting values:                   Molar mass of benzene=78.11 grams per mole

No of molecules in C6H6= 156/78.11 * 6.02*10^23    

No of molecules in C6H6=12.02 *10^23 molecules.

So number of molecules in 156 grams of benzene is 12.02 * 10^23 molecules.
