The rate of diffusion of methane gas, CH4, is four times the rate of diffusion of an unknown gas under the same conditions of temperature and pressure. What is the molar mass of the unknown gas

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Hope the image of the frequency formula

Higher temperature = molecules move around faster. and vice versa.
