Use the ideal gas law to solve for the moles of a gas that occupies 25.61 L at 5.13 am and 27 00. (R =
0.0826 L*atmlmol*K Select one: v O \323 moles O 2.46 moles O 5.32 moles O 1.23 moles

the ideal gas equation is

Pressure * Volume = moles * R * Temperature

where:

Pressure is in atmospheres

Volume is in liters

R is the gas constant = 0.0826 L*atm/K mol

Temperature in Kelvin

In this case we want to find the number of moles so rearrange the equation to get moles:

moles = Pressure * volume / [R * Temperature]

given information:

Pressure = 5.13 atm

Volume = 25.61 L

Temperature = 27 C

Change Celsius to Kelvin

Kelvin = Celsius + 273.15

Kelvin = 27 + 273.15

Kelvin = 300.15 K

plug in the values in the equation

moles = (5.13 atm*25.61 L) / (0.0826 * 300.15)

moles = 5.299178

The most suitable answer is

"5.32 moles"
