Guys I'm weak in heat and kinetic theory, so I'm gonna need extra guide and pointers from you guys to solve this and the coming questions. Thank you.

A constant-volume gas thermometer of volume 0.001m3 contains 0.05mol of a gas and is used to deduce values of temperature on the assumption that the ideal gas law is obeyed. In fact, one mole of the gas satisfies the relation ,
where a correct for intermolecular forces and b corrects for the effective size of the gas molecules.
(i) What form of the equation should be used for x moles of gas? Explain your answer.
(ii) Given that the thermometer was calibrated at the triple point of water, use the data below to calculat the error when the thermometer is used to measure a temperature near to that of boiling water: a = 0.08 Pa m6 mol -2; b = 3E-5 m3 mol-1.

Attempt:
I honestly don't know. Pointers anyone?

It's been a while since you posted and nobody's replied yet...maybe you should check out MarkedbyTeachers.com, TSR's sister site. It has the largest library of essays in the UK.

They've got over 181,000+ coursework, essays, homeworks etc.. all written by GCSE, A Level, University and IB students across all topics. You get access either by publishing some of your own work, or paying £4.99 for a month's access. Both ways give you unlimited access to all of the essays.

All their documents are submitted to Turnitin anti-plagiarism software, so it can't be misused, and the site's used by hundreds of thousands of UK teachers and students.
