meh Posted May 11, 2011 Report Share Posted May 11, 2011 Calculators have never been used on a p1 for science =/ All the numbers (if you see what there actually testing you on) should work out into mental math really easily =/ Do you happen to remember one of the questions?For the second question I believe the calculation you had to do was (1.7/85) to get the number of moles, then divided by the volume 0.2 to get the concentration. Totally couldn't do that in my head aha =/ that's why I'm not in math IB. Does anyone know what the answer is? Assuming I remembered the numbers correctly it looks like it should be 0.1 but I don't remember if that was answer A or B. Reply Link to post Share on other sites More sharing options...
