Question

calculate the mass of atoms present in 0.5 moles of nitrozen
(n) (N=14u)​

Answer 1

Answer:7 g

Explanation: Mole = _Mass_

Molar mass

So 0.5=Mass÷14 u

Mass=14×0.5=7g

Answer 2

Given,

Number of moles = 0.5

Molecular mass = 14u

To find,

The mass of the atoms of the given substance.

Solution,

To solve this mathematical problem,we have to apply the general formula of the molar concept.

The mathematical formula is,

Number of moles = Mass of the given substance/ Mass of the one mole of the given substance

Number of moles = Mass of the given substance / Molecular mass of the given substance

0.5 = Mass of the given substance/ 14

Mass of the given substance = 14×0.5 = 7 grams

Hence,the mass of the given substance is 7 grams.
