Question

Q - If 29 mg of nitrogen dissolves in water at 0°c and 760 Torr nitrogen pressure , how much N₂ will dissolve in 1L of water at 0°c and 5atm N₂ pressure ?​

Answer 1

Answer:

molar mass of Nitrogen= 29 g

one mole of nitrogen dissolve in water at

0° centigrade at 1 atm pressure

at 5 atm pressure the amount of Nitrogen dissolved would decrease by factor of 5

or, amount of nitrogen dissolve = 1/5 mole = 0.2 mole = (1/5 × 29) g = 5.8 g

Answer 2

Molality =60123×8971000 =2. 28 mol kg−1.
