What is the molecular formula for the compound with a formula mass of 58.12 and an empirical formula of c2h5?

C₄H₁₀

Explanation:

The empirical formula is the reduced formula of the molecule. So, calling n the number of empirical formulas, the molecule formula will be:

n(C₂H₅)

The molar mass of C is 12 g/mol, and of H is 1 g/mol. So, the total mass will be:

nx(2x12 + 5x1) = 58.12

29n = 58.12

n = 2

Then, the molecular formula is:

2(C₂H₅) = C₄H₁₀

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
