How many grams of benzene would be produced when 135.5 gms of phenyl magnesium chloride is trated with 224 ml of ethyne at STP ?

Explanation

`{:("2 Moles ",22.4Ldarr,"2 Moles",),(,"Limiting reagent ",=156"gms",):}`
`because22400mlH-C-=-H" gives=156 gms of benzene"`
`:.1mlH--=C-H" gives"=(156)/(22400)xx224=1.56" gm of Benzene"`
`:.224mlH-C-=-H"gives =1.56 gms "]`
