Under normal conditions, when salt is added to water THE SALT DISSOLVES IN THE WATER THEREBY INCREASING THE BOILING POINT OF THE WATER.
When salt is added to water, the sodium and the chlorine ions in the salt separate and attach themselves to water molecules, this leads to the dissolution of the salt. Dissolving salt in water automatically increase the temperature at which the water will boil; the temperature will be greater than 100 degree Celsius. <span />
We can use the ideal gas law equation to find the volume of N₂ gas at STP
PV = nRT
where
P - standard pressure - 101 325 Pa
V - volume
n - number of moles - 21.0 g / 28 g/mol = 0.750 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - standard temperature - 273 K
substituting the values in the equation
101 325 Pa x V = 0.750 mol x 8.314 Jmol⁻¹K⁻¹ x 273 K
V = 16.8 L
volume of N₂ at STP is 16.8 L
