How many moles of O2 gas are there in a 1.0 L container which contains 0.12 atm of O2 gas at 25 ºC? (The correctly abbreviated unit in the correct case is required for this question.)

The number of moles of oxygen gas in the container is 0.0049 moles

Explanation:

To calculate the moles of oxygen gas, we use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 0.12 atm

V = Volume of the gas = 1.0 L

T = Temperature of the gas =

R = Gas constant =

n = number of moles of oxygen gas = ?

Putting values in above equation, we get:

Hence, the number of moles of oxygen gas in the container is 0.0049 moles

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.
