Question

at 273 degrees celsius 1 atm pressure the volume of gas is 44.8 lit.the number of moles of gas is

Answer 1

$\huge{\underline{\underline{\pink{\mathfrak{Answer :}}}}}$

$\tt Given \begin{cases} \sf{Pressure \: (P) \: = \: 1 \: atm} \\ \sf{Volume \: (V) \: = \: 44.8 \: L} \\ \sf{R \: = \: 0.082 \: L \: atm \: mol^{-1} \: K^{-1}} \\ \sf{Temperature \: = \: 273^{\circ}C \: = \: 546 K} \end{cases}$

We know that Ideal Gas equation is :

$\LARGE{\boxed{\boxed{\tt{PV \: = \: nRT}}}}$

Where, n is number of moles of Gas atoms

____________[Put Values]

$\large \rightarrow {\sf{n \: = \: \dfrac{PV}{RT}}}$

$\large \rightarrow {\sf{n \: = \: \dfrac{(1)(44.8)}{(0.082)(546)}}}$

$\large \rightarrow {\sf{n \: = \: \dfrac{\cancel{44.8}}{\cancel{44.77}}}}$

$\large \rightarrow {\sf{n \: = \: 1}}$

$\Large{\underline{\boxed{\sf{\therefore \: Number \: of \: Moles \: = \: 1}}}}$
