How many molecules of benzene are there in 1L of c6h6

1.	How many molecules of benzene are there in 1L of c6h6
Answer» tion:specific GRAVITY of BENZENE is 0.88specific gravity=(density of substance)/(density of water at 4°C)Let density of benzene= X⇒0.88= X/1 [density of water at 4°C= 1 gm/ml]⇒X= 0.88Density of benzene = 0.88 gm/mlMass = Density × Volume⇒MASS= 0.88 gm/ml × 1000 ml⇒mass=880 gmMolar mass of benzene= 72 + 6 = 78Moles of benzene= 880 gm/ 78 gm = 11.282 MOLES1 moles ⇒ 6.022 × 10^23 molecules11.282 moles ⇒ 11.282 × 6.022 × 10^23 molecules =6.79 × 10^24 moleculesanswer: 6.79 × 10^24 molecules
