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

`1.385\ \text{moles}`

Step-by-step 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=(m)/(M)`

`\Rightarrow n=(98.2)/(70.9)`

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

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