Ответ:
Polar molecules occur when two atoms do not share electrons equally in a covalent bond. ... If the electronegativity difference between the atoms is greater than 2.0, the bond is ionic. Ionic compounds are extremely polar molecules.
Explanation:
Ответ:
= 3.064 g/L
Explanation;Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Number of moles is 1 since one mole has a mass equivalent to the molar mass.
Therefore; We can find the volume and thus get the density.
V = nRT/P
= (1 × 0.08206 × 498 )/ 0.939
= 43.52 L
But; density = mass/volume
Therefore;
Density = 133.34 / 43.52
= 3.064 g/L
