![**Using Mass Density to Find Mass or Volume**
A chemistry student needs 90.0 mL of pentane for an experiment. By consulting the *CRC Handbook of Chemistry and Physics*, the student discovers that the density of pentane is 0.626 g/cm³. Calculate the mass of pentane the student should weigh out.
Round your answer to 3 significant digits.
