Answer:
3.51 g/mL
Step-by-step explanation:
Density can be found using the equation: density = mass / volume.
In this case, mass is given in grams (g) and volume is given in milliliters (mL).
You can find the density of the diamonds by plugging the given values into the formula and simplifying.
Density = mass (g) / volume (mL)
Density = 6.21 g / 1.77 mL
Density = 3.51 g/mL
