Answer 1

Answer:

A 320 ml sample of a dry gas is collected at 47°C and 740 mm of Hg. What is the volume at 7°C and 560 mm of Hg? *

Explanation:

plz give me answer my question

Answer 2

370 ml

Explanation:

Given,

V1 = 320 ml

T1 = 273+47 = 320 K

P1 = 740 mmHg

T2 = 273+7 = 280 K

P2 = 560 mmHg

V2 = ?

Now,

Volume of dry gas at STP

V = (740x320x273)/(760x320)

V = 265.815789 ml

Again,

V2 = (760x265.815789x280)/(560x273)

V2 = 370 ml
