How many mL of an impure liquid CS2 mixture (density 1.26 gmL-1) which contains 93.0% of CS2 by mass, must be burned to obtain 12.8g SO2?
I cannot get this question! Thanks
one mole of CS2 yields two moles of SO2 (count the S atoms).
determine the moles of SO2 in 12.8g
divide that by two, to get moles of CS2.
divide that by .93 to get mass of CS2.
divide that by the density to get mL
