Amount of dry h2 are there in the sample, the vapor pressure of water at 23 °C is 0.023 grams.
Vapour pressure is a measure of the tendency of cloth to trade into the gaseous or vapor state, and it increases with temperature. The temperature at which the vapor stress at the floor of a liquid will become equal to the pressure exerted by the environment is known as the boiling factor of the liquid.
Calculation:-
V = 0.568 L
T = 23 + 273 = 296 K
P = 735 torr = 0.967 atm
PV = nRT
n = PV/RT
= 0.967 × 0.568 / 0.08206 × 296
= 0.549/24.289
n = 0.023 mol
moles = mass/molar mass
mass = 0.023 × 1.008
= 0.023 gram
Vapor pressure or equilibrium vapor strain is described because of the stress exerted through a vapor in thermodynamic equilibrium with its condensed levels at a given temperature in a closed machine. The equilibrium vapor strain is an indication of a liquid's evaporation fee.
