Identify the given quantities: density (\( \rho \)) = 2.5 g/mL and volume (\( V \)) = 15 mL.
Recall the formula that relates mass (\( m \)), density (\( \rho \)), and volume (\( V \)):
\[ m = \rho \times V \]
Substitute the given values into the formula:
\[ m = 2.5 \text{ g/mL} \times 15 \text{ mL} \]
Multiply the density by the volume to find the mass:
\[ m = 2.5 \times 15 \text{ g} \]
The result from the multiplication gives the mass of the liquid in grams.
