Question

The number of moles of H 2 in 0.224 L of hydrogen gas at STP ( 273 K , 1 atm ) assuming ideal gas behaviour is (A) 1 (B) 0.1 (C) 0.01 (D) 0.001

Tardigrade Admin · Accepted Answer

Applying PV = nRT, P =1 atm , V =0.224 L , R =0.821 L atm K -1 mol -1 T =273 K n=(1 × 0.224/0.0821 × 273)=0.01
