p1=40mm
p2= 760mm(at S.T.P)
v1=700ml
v2=?
t1=15°c. = 15+273=288°k
t2= 0°c. = 0+273=273°k
=
\frac{p1 \times v1}{t1} = \frac{p2 \times v2}{t2}
t1
p1×v1
=
t2
p2×v2
\frac{40 \times 700}{288} = \frac{760 \times v2}{273}
288
40×700
=
273
760×v2
972.223 = \frac{760 \times v2}{273}972.223=
273
760×v2
\frac{265416.879}{760} = v2
760
265416.879
=v2
