# A Sample of Carbon Dioxide Occupies 30 Cm3 at 15°C and 740 Mm Pressure. Find Its Volume at Stp. - Chemistry

Numerical

A sample of carbon dioxide occupies 30 cm3 at 15°C and 740 mm pressure. Find its volume at STP.

#### Solution

V = 30 cm3
P = 740 mm
T = 288 K
P1 = 760 mm
V1= ?
T1 = 273 K

Using gas equation,

"PV"/"T" = ("P"_1 "V"_1)/"T"_1

(740xx30)/288 = (760xx"V"_1)/273

"V"_1 = 27.7 "cm"^3

Concept: Standard Temperature Pressure (S.T.P.)
