When all the gas has been collected, the pressure in the flask is measured to be 0.240 atm mass and number of moles of dinitrogen difluoride gas that were collected. Round your answer to 3 significant digits. mass: Oa mole: Check 5-26 O Type here to search

Explanation / Answer

PV = nRT

P = Pressure = 0.240atm

V = Volume = 40.0L

n = moles

R = Gas Constant = 0.0821Latm/moleK

T = Temp = -3.0? = -3.0 + 273 = 270K

n = PV/RT

= 0.240atm * 40.0L / 0.0821Latm/moleK * 270K

n = 0.433moles

Moles = 0.433moles

Molar mass of dinitrogen difluoride = 66.01g/mol

Mass = moles* Molar mass = 0.433mol * 66.01g/mol = 28.6g

Mass = 28.6g
