Question

How many grams are converted in 2.00 mol of neon?

Answer 1

Hint:To calculate the number of ions first we have to calculate the number of moles of the given element as the number of moles is already given, then the mass can easily be calculated. A mole is generally used as a unit for the number of atoms or molecules or particles of a material.

Complete answer:
The mole is a measurement or it is the basic unit which helps to calculate the amount of substance present in the given sample. 1 mole of a number is equal to Avogadro’s constant ${{N}_{A}}$.
Number of mol is calculated by ratio of given mass to the molar mass.
Number of mol of neon = $\dfrac{\text{given mass}}{\text{molar mass}}$
Given,
Number of moles = 2 mol
Molar mass of neon = 20.2 g/mol
Hence the given mass will be equal to the product of molar mass and the number of moles of neon i.e.
Given mass = $=20.2\times 2=40.4g$
Hence, 40.4 grams are converted in 2.00 mol of neon.

Note:
1 mole=$6.022X{{10}^{23}}$ particle or atoms or molecules or electrons or protons etc. The number of the constituent particles of atoms such as molecules or atoms or ions present in a given sample is related with the mass of the substance present in the sample using Avogadro's number. The SI unit of Avogadro’s number is inverse of mole i.e.$mol{{e}^{-1}}$
Avogadro’s number is dimensionless. It also helps to relate the molar volume of a substance to the average volume which is occupied by one of the particles.
