What is the volume of 5.40 mole of O2?

Answers

The volume occupied by 5.40 mole of O2 is 120.96 L.

What is molar volume?

The term molar volume refers to the volume of one mole of a gas. According to Professor Avogadro, the volume of one mole of a gas is 22.4 L.

Now, we are asked to find the volume of 5.40 mole of O2.

If 1 mole of O2 occupies a volume of 22.4 L

5.40 mole of O2 occupies 5.40 mole * 22.4 L/1 mole = 120.96 L

The volume occupied by 5.40 mole of O2 is 120.96 L.

Chlorine gas occupies a volume of 1. 2 liters at 720 torr pressure. What volume will it occupy at 1 atm pressure? Note: 760 torr = 1 atm

I NEED HELP!! (mostly w/ torr and atm part)

Answers

Answer:

V2 = 1.14

Explanation:

V1 = 1.2L

P1 = 720 torr (÷ by 760 to get atm. Because 1 atm equal 760 torr) = 0.95 atm

P2 = 1 atm

V2 =?

Follow the equation below to solve this question

P1V1 = P2V2

0.95 x 1.2 = 1 x V2

If you had 0.2M solutions of nitric and carbonic acids, which solution would have a lower pH?
Why?

Answers

0.2 M each of nitric acid and carbonic acid will have the same pH.

pH

The pH of substances is mathematically given as:

pH - -log [H+]

Nitric and carbonic acid dissociates according to the following:

HNO3 ---------> H+ + NO3-

H2CO3 -------> H+ + HCO3-

Thus, both acids ionizes to produce the same number of moles of H+, thus, producing the same pH

1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it

2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth

3) mass and how far away you are from the object

4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)

5) when distance increases, gravity decreases (again I do not remeber by how much)
