Good question!! I’ll try to help you the best I can!

⓵ First off, you have to know that acetone has a density of 0.7857 g/cm³

⓶ You also need to know that 1mL = 1cm³

⓷ Once you know that, the rest is pretty easy you’ll see! The next step is a cross product to find out how many cm³ are in 6.72g :

0.7857 g → 1 cm³
6.72 g → × cm³

→ (1 • 6.72) ÷ 0.7857 = ×

→ 6.72 ÷ 0.7857 = ×

→ 8.55 ⋍ ×

Which means that for 6.72g of acetone, you have a volume of about 8.55cm³.

⓸ 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! ☻
