The molecular weight of a gaseous substance is 200: What is the volume of the bagof the substance at NTP? |
|
Answer» ong>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 |
