What is the density of fluorine gas, f2, at stp? e) 0.848 g/l b) 1.18 g/ l c ) 1.70 g/l d) 0.589 g/l

C ) 1.70 g/L

Explanation:

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Also,

Moles = mass (m) / Molar mass (M)

Density (d)  = Mass (m) / Volume (V)

So, the ideal gas equation can be written as:

PM=dRt

At STP,

Pressure = 1 atm

Temperature = 273.15 K

Molar mass of fluorine gas = 38 g/mol

Applying the equation as:

1 atm × 38 g/mol = d × 0.0821 L.atm/K.mol × 273.15 K

⇒d = 1.70 g/L

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
