Answer:
Velocity = wavelength x frequency
Wavelength = Velocity / frequency
From the above,
Wavelength is inversely proportional to frequency since the velocity of electromagnetic wave is constant.
So as the wavelength increases, the frequency decreases and vice versa
Temperature can be calculated using the average kinetic energy. The ideal gas equation is being related to the average molecular kinetic energy.

T = 3866 x 2 / 8.3145 x 3 = 309.98 K or 36.83 degrees Celsius
Answer:
The formula weight of the compound is
46.069 g/mol.
Explanation:
Determine the molar mass from the empirical formula (C2H6O) by multiplying the molar mass of each element in the compound by the number of atoms of it and adding the resulting masses of the elements:
molar mass of C2H6O = (2 × 12.011 g/mol) + (6 × 1.008 g/mol) + (1 × 15.999 g/mol) = 46.069 g/mol.
