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

just finished the assignment

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
