# What is the density of a substance if 3.00 mL has a mass of 3.85 grams?

Jan 17, 2018

${\rho}_{\text{density"="mass of stuff"/"volume of stuff}}$

#### Explanation:

And looking at dimensions, for chemists, we typically use $g \cdot m {L}^{-} 1 \equiv g \cdot c {m}^{-} 3$....

And so we take the quotient...

${\rho}_{\text{stuff}} = \frac{3.85 \cdot g}{3.00 \cdot m L} = 1.28 \cdot g \cdot m {L}^{-} 1$...

Would this stuff float on water? Why or why not?
