What is the volume, in liters, occupied by 1.73 moles of N2 gas at 0.992 atm pressure and a temperature of 75º C? (R value- 0.08206)

48.70 is the volume, in liters, occupied by 1.73 moles of Nitrogen gas at 0.992 atm pressure and a temperature of 75º C.

Explanation:

Data given:

number of moles of nitrogen gas = 1.73 moles

pressure of the gas = 0.992 atm

temperature of the gas = 75 degrees or 273.25 + 75 = 348.15 K

R (gas constant) = 0.08206 L atm/molesK

volume of the nitrogen gas under these conditions =?

The formula used is of ideal Gas Law:

PV = nRT

Rearranging the equation to get,

V =

putting the values in the equation:

V =

  = 48.70 Litres

the volume of the gas is 48.70 litres from the standard values used in the equation.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
