What is the mass of 5 moles of chlorine gas? [ Atomic mass of Cl = 35.5u]

Answered by admin @ 03/08/2021

Hi friend,

Here is your answer...

As per mole concept,there is a general formula for finding "n" (no.of moles).

:- n =Given mass of a substance/Molar mass
$n \: = given \: Mass \: of \: the \: substance \div molar \: mass$
As per formula,

molecular mass of cl only exists as cl2 gas . :-mol.mass of cl gas =35.5 g

then by sub.

n=5moles

5 = x/35.5

x =35.5 ×5

x =177.5 g

mass of cl gas =177.5 g

Hope this helps you a little!!!!
