1)a fixed mass of gas occupies a volume of 20cm^3 at a pressure of 700mmHg assuming that the temperature remains constant,what will be the volume of the gas at 750mmHg to 3.s.f [ii]A gas volume is 70cm^3 at a temperature of 15¤c and 750mmHg.calculate it volume to 3.s.f at s.t.p
-
p1v1= p2v2
700 x 20 = 750 x v2
v2= 18.7 cm3
p1v1/t1= p2v2/t2, where t = temp. oK
(750 x 70)/288 = (760 x v2)/273
v2= 65.5 cm3
700 x 20 = 750 x v2
v2= 18.7 cm3
p1v1/t1= p2v2/t2, where t = temp. oK
(750 x 70)/288 = (760 x v2)/273
v2= 65.5 cm3
