How many molecules of benzene arethere in 1Lof C6H6 [d=0.88g/cm3]??? |

Answer» tion:Given -1 L C6H6, density(d) = 0.88 g/cm³To FIND -How many molecules of BENZENE are there in 1 L of C6H6Solution -d = m/v0.88 = m/1 × 1000M = 0.88 × 1000m = 880Now, As we know that -MOLE = mass/GMMn_{C6H6} = 880/78n_{C6H6} = 11.282Then, Number of molecules = n × 6.022 × 10²³= 11.282 × 6.022 × 10²³= 67.94 × 10²³Hence, The number of molecules present in 1 L of C6H6 is 67.94 × 10²³. |
