PV=nRT T=50° C=323.15 K P=740 mm of Hg=(740/760)atm V=? moles (n)=(4 . 75/26) V=(4 . 75/26)× (0 . 0821 × 323 . 15/740)× 760 V=4.97=5 Lit

Q. The volume occupied by $4.75 g$ of acetylene gas at $5 0^{\circ} C$ and $740 mm H g$ pressure is ______ $L .$
(Rounded off to the nearest integer) (Given $R = 0.0826 L$ atm $K^{- 1} m o l^{- 1}$ )

$P V = n RT$
$T = 5 0^{\circ} C = 323.15 K$
$P = 740 mm$ of $H g = \frac{740}{760} a t m$
$V = ?$
moles $(n) = \frac{4.75}{26}$
$V = \frac{4.75}{26} \times \frac{0.0821 \times 323.15}{740} \times 760$
$V = 4.97 = 5 L i t$

Q. The volume occupied by 4.75g of acetylene gas at 50∘C and 740mmHg pressure is ______L. (Rounded off to the nearest integer) (Given R=0.0826L atm K−1mol−1 )
