# A sample containing 33.42 g of metal pellets is poured into a graduated cylinder initially containing 12.7 mL of water, causing the water level in the cylinder to rise to 21.6 mL. What is the density of the metal?

$\text{Density"="Mass"/"Volume}$ $\cong$ $3 \cdot g \cdot m {L}^{-} 1$
(33.42*g)/((21.6*mL-12.7*mL) $=$ ??*g*mL^-1
