Verified step by step guidance1
Recall the formula for density, which is defined as mass divided by volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Identify the given values from the problem: mass = 10 grams and volume = 2 mL.
Substitute the given values into the density formula: \(\text{Density} = \frac{10\ \text{g}}{2\ \text{mL}}\).
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Express the units clearly as grams per milliliter (g/mL) to complete the density calculation.
