let's  assume that the f₂  gas  has ideal gas behavior. 

then we can use ideal gas formula,pv = nrt where, p is the pressure of the gas (pa), v is the volume of the gas (m³),  n is the  number of moles of gas (mol), r is the universal gas constant ( 8.314 j mol⁻¹ k⁻¹) and t is temperature in kelvin.

moles = mass / molar mass

molar mass of f₂ =  38 g/mol

mass of  f₂  = 76 g

hence, moles of f₂ = 76 g / 38 g/mol = 2 mol

p = ? v =  1.5 l = 1.5 x 10⁻³  m³

n = 2 mol

r =  8.314 j mol⁻¹ k⁻¹ t = -37 °c = 236 k by substitution,

p x  1.5 x 10⁻³  m³ = 2 mol x 8.314 j mol⁻¹ k⁻¹ x 236 k

                          p = 2616138.67 pa

                          p =  25.8 atm = 26 atm

hence, the pressure of the gas is 26 atm.

answer is "a".

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
