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

Solve: A certain light bulb containing argon has a pressure of 1.20 atm at 18°C. If it

will be heated to 85°C at constant volume, what will be the resulting pressure? Given: P₁ = 1.20 atm.                                                                             P₂ = ?

T₁ = 180C + 273.15= 291.15 K                            T₂ = 850C + 273.15=358.15 K

Solve: Helium gas has a volume of 250 mL at 0°C at 1.0 atm. What will be the final

pressure if the volume is reduced to 100 mL at 45°C?

Given: V1 = 250mL                                                       V2 = 100 mL

T₁ = 00C + 273.15= 273.15 K                     T₂ = 450C + 273.15=318.15 K P₁ = 1 atm                                                                    P₂ = ?

Solve: A certain light bulb containing argon has a pressure of 1.20 atm at 18°C. If it

will be heated to 85°C at constant volume, what will be the resulting pressure? 

2.   A tank ( not rigid) contains 2.5 litres of helium gas at 28⁰C . At constant pressure, what will be the volume of the tank after heating it and its content to 43⁰C temperature?
