When an electric current is passed through a solution containing dilute tetraoxosulphate (Vi) acid, 190 cm³ of hydrogen gas is evolved. if the measurements were made at 26°C and 736 mmHg, what is the volume of hydrogen at s.t.p.?

164 cm³

168 cm³

179.1.cm³

201.5cm³

p1=736mmhg
p2=760mmhg
v1=190cm3
v2=?
T1=26•c +273=299k
T2=273k

P1 V1/T1=P2 V2/T2
V2=P1 V1 T2 /P2 T1

731*190*273/760*299=168cm3
