Density is mass per volume. So each 1mL of your substance weighs 8.66g. With 73.5g total substance, you have 73.5/8.66 mL of substance. 

Since both figures in the question are 3 s.f., your answer should also be to 3 significant figures. Take the first 3 digits, and look at the fourth - if it's 5 or higher, round the third digit up. 

(Did you get 8.49?)
