<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds
will contain both metals and non-metals, or at least one polyatomic
ion. *Acids will always include the (aq) symbol beside the formula, and
the name will include the word acid.</span>
Answer:
2 g/mL
Explanation:
Density can be calculated using the ratio:
Density = mass (g) / volume (mL)
Since you have been given both the mass and volume of the liquid, you can calculate the density.
Mass = 6 grams (g)
Volume = 3 milliliters (mL)
Density = mass / volume
Density = 6 g / 3 mL
Density = 2 g/mL
