Find the area of the rectangle whose length is 3 m and whose width is 13 m. Find the area of the rectangle whose length is 3 m and whose width is 13 m.

5.  The way I do these problems is setting up the equation as follows:

P1V1/T1 = P2V2/T2

The units of volume and pressure can be substituted as given, since they are in relation to one another, however, the final answer must match the units provided in the question.  Also, temperature must be converted to Kelvins before the equation can be used.

V1 = 50 cm^3

P1 = 825 Hg/mm

T1 = 15C = 288K

P2 = 750 Hg/mm

T2 = 47C = 320K

V2 = ?

Solve:

P1V1/T1 = P2V2/T2

(825)(50)/(288) = (750)V2/(320)

143.23 = 2.34V2

V2 = 61.21 cm^3
