What is the correct formula for finding Density?

I’ll give you a trick they taught us in school to remember it.

“Density is equals to a broken heart.”
Density = mass / volume
D = m / v

When you write it doing on a paper and put the m over the v with the division symbol, it’ll look like a broken heart!
Hope this will help you :)
