Question

A chemist measures the amount of chlorine gas produced during an experiment. He finds that 98.2 of chlorine gas is produced. Calculate the number of moles of chlorine gas produced.

Answer 1

Answer:

$1.385\ \text{moles}$

Explanation:

$m$ = Mass of chlorine gas produced = $98.2\ \text{g}$

$M$ = Molar mass of chlorine gas $Cl_2$ = $70.9\ \text{g/mol}$

Number of moles is given by

$n=\dfrac{m}{M}$

$\Rightarrow n=\dfrac{98.2}{70.9}$

$\Rightarrow n=1.385\ \text{moles}$

Number of moles of chlorine gas produced is $1.385\ \text{moles}$.
