How many moles of an ideal gas is contained in a cylinder with a volume of 137 ml, a pressure of 52.0 cm of hg and a temperature of 98 degrees fahrenheit? show work!

The number of moles of ideal gas are 0.0037 moles

Explanation:

To calculate the mass of helium gas, we use the equation given by ideal gas:

PV = nRT

where,

P = Pressure of helium gas = 52 cmHg = 520 mm Hg    (Conversion factor: 1 cm = 10 mm)

V = Volume of the helium gas = 137 mL = 0.137 L   (Conversion factor: 1L = 1000 mL)

n = number of moles of gas = ?

R = Gas constant =

T = Temperature of helium gas =    (Conversion factor:  )

Putting values in above equation, we get:

Hence, the number of moles of gas is 0.0037 moles.
