1.	In which case is the number of molecules of water maximum ?
Answer» `10^(-3)`mole of water 18 ml of water 0.00224 L of water VAPOURS at 1 atm and 273 K 0.18 g of water Solution :(A) `10^(-3)` mole water (B) 18 ml water = 18 g water = 1 mol water (C) 0.00224 L water vapour at (STP) `(0.00224)/(22.4) = 0.0001` mole `H_2O` (D) 0.18 g water = `(0.18)/( 18) = 0.1 ` mol water Among the four options, option (B) has maximum number of MOLES so it has maximum MOLECULES.
