Academics

After the label fell off a bottle containing a clear liquid believed to be benzene, a chemist measured the density of the liquid to verify its identity. A 25.0-{\rm mL} portion of the liquid had a mass of 21.95 {\rm g}. A chemistry handbook lists the density of benzene at 15 ^\circ {\rm C} as 0.8787 {\rm g/mL}.
