Ne(g) effuses at a rate that is times that of br2(g) under the same conditions.

Answer : The Ne(g) effuses at a rate that is 2.828 times that of under the same conditions.

Solution : Given,

Molar mass of neon = 20 g/mole

Molar mass of bromine = 160 g/mole

Rate of diffusion : It is defined as the rate of diffusion is inversely proportional to the square root of the molar mass of the gas.

Formula used :

where,

= Rate of diffusion of neon gas

= Rate of diffusion of bromine gas

= Molar mass of neon gas

= Molar mass of bromine gas

Now put all the given values in this formula, we get

Therefore, the Ne(g) effuses at a rate that is 2.828 times that of under the same conditions.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
