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

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

the dependant variable is spilled water

the independent is the heat
