determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. what is the number of moles present?

Answer : The number of moles of air present is, 0.055 mole

Solution :

Using ideal gas equation :

where,

P = pressure of the gas = 750 torr = 0.98 atm      (1 atm = 760 torr)

V = volume of the gas = 1.35 L

T = temperature of the gas =

R = gas constant = 0.0821 Latm/moleK

n = number of moles of air = ?

Now put all the given values in this formula, we get the number of moles of air present.

Therefore, the number of moles of air present is, 0.055 mole

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
