1. A balloon contains 14.0 L of air at a pressure of 760 torr. What will the volume of the air be when the balloon is taken to a depth of 10 ft in a swimming pool where the pressure is 981 torr? The temperature of the air does not change.

1. My grandmother was hospitalized at the Community Hospital due to difficulty in breathing. The nurse supported her breathing with the aid of oxygen gas. The nurse noted that the tank of oxygen gas has a volume of 14.0L and a pressure of 1 atm. Find the volume of the oxygen when its pressure is changed to 1.2 atm while the temperature is held constant.

Given: V₁=14.0 L, P₁= 1.0 atm, P₂= 1.2 atm

1.  If 15.0 L Neon at 60 0C is heated at constant pressure, what temperature will it have if it occupies a volume of 4.50 L?

1. A hot air balloon has a volume of 2800 m3 at 990C. What is the volume if the air cools to 800C.

Given:     V₁ = 2800m3

T₁=99°C+273K = 372 K        T₂ =80°C +273K =353K

Unknown: V₂

Formula:

Solution:

Final answer:

Cu + S₈ -> Cu₂S

Calculate the pressure, in atm, required to compress a sample of helium gas from 5.00 L

(at 1.00 atm) to 2.00 L.

CCl4 + SbF3 = CCl2F2 + SbCl3

How many grams of CCl4 are needed to react with 5.0 mol SbF3?

it requires two sticks of butter to make a batch of 20 cookies. how much butter will it take to make 150 cookies

Solve: What is the volume of a container that can hold 0.50 mole of gas at 25.0°C and 1.25atm?

Given: V₁ = ?

n = 0.50 mole

T = 250C + 273.15= 298.15 K

P = 1.25 atm

R = 0.0821 L atm/ mol K

Solve: What will be the final volume of a 5.00 L He gas which contains 0.965 mole at 30°C and 1.00 atmosphere, if the amount of this gas is increased to 1.80 moles provided that the temperature and pressure remains unchanged?

Given: V₁ = 5.00L                                                       V₂ = ?

_T𝟏 = 0.965 mole                                            T_𝟐 = 1.80 moles
