Answer:Good question!! I’ll try to help you the best I can!
First off, you have to know that acetone has a density of 0.7857 g/cm^2
You also need to know that 1mL = 1cm^3
Once you know that, the rest is pretty easy you’ll see! The next step is a cross product to find out how many cm^2 are in 6.72g :
0.7857 g → 1 cm^3
6.72 g cm^3
(1 * 6.72) ÷ 0.7857 = x
6.72 ÷ 0.7857 =x
8.55
Which means that for 6.72g of acetone, you have a volume of about 8.55cm^3.
Finally, since we’ve established in the beginning that 1cm³ = 1mL, it’s easy to answer your question!
The volume, in millilitres, of 6.72g of acetone is about : 8.55mL
There you go, I really hope this helped, if there’s anything just let me know!
