Question

(a) A laser spectroscopist produces benzene clusters by seeding benzene within helium in a supersonic expansion. Benzene and helium are mixed within a gas cylinder and stored in a lab at 22 °C. What are the relative speed of the benzene molecules and helium atoms within the cylinder? [4 marks]

Answer 1

For helium 1370ms^-1= 300k

? = 295k

1370×295/300

= 1347.167ms^-1
