Question

a gas sample occupies 55ml at 182°C and 3 atm.Wjat will be the volume of the sample at S T P?
Answer 99ml​

Answer 1

Answer:

99 ml

Explanation:

V1 = 55 mL

P1 = 3 atm = 2280 mm Hg

T1 = 182°C =182 +273 K = 455 K

V2 = ?

P2 = 760 mm Hg

T2 = 273 K

(ALWAYS REMEMBER AT STP, P = 760 mm Hg and T = 273K)

By Gas Equation,

$\frac{V1P1}{T1} = \frac{V2P2}{T2}\\\\V2 = \frac{V1P1T2}{T1P2}\\\\SUBSTITUTING, \\\\V2= \frac{273X 55 X2280}{455X 760 }$

= 99 mL
