Question

The molecular weight of a gaseous substance

is 200: What is the volume of the bag
of the substance at NTP?​

Answer 1

Explanation:

First , we need to find the moles of the gaseous substance .

As per the formula ,

\begin{gathered}\implies\mathtt{ moles = mass / molar\: mass} \\\end{gathered}

⟹moles=mass/molarmass

⇒ moles = 5 / 200

⇒ moles = 1 / 40

⇒ moles = 0.025

As per the relation ,

\begin{gathered}\implies \mathtt{moles = volume / 22.4 L (NTP )} \\\end{gathered}

⟹moles=volume/22.4L(NTP)

⇒ volume = moles x 22.4

⇒ volume = 0.025x 22.4

⇒ volume = 0.56 L

The volume of the substance at NTP is
