& GAS LAWS AND IDEAL GAS EQUATIONFind the approximate number of moleculescontained in a vessel of volume 7 litres at 0°C at1.3 x 105 pascals |
|
Answer» 1.3 × 10^5 pascal in pressure in atm is = 1.283 atm , 0° C = 273 K now using PV = nRT => 1.283*(7) = n*(0.082057 L atm mol-1K-1)× 273 => n = 0.401 moles no..of molecules = 0.4Na |
