Defined as the amount of mass per unit of volume. Density = mass (grams) You can measure volume by displacement of water using a graduated cylinder. V= volume V water with object – V water without object = V object Summary: volume (mL)

Title: Measurement Lab Purpose: To hone your measurements skills using various scientific instruments.

Table 1: Measurement of Various Objects Using the Metric System. Mass of two full containers Mass of 1 empty container Mass of powder only (CuSO 4 ) (do not pour it out; use a calculator) Volume of H 2 O in graduated cylinder Volume of H 2 O in Erlenmeyer flask Mass of metal rod Width (distance) of tabletop Width (distance) of piece of paper Temperature of room

Conclusion Questions: Metric to Metric conversions 1. 1) Convert the number of grams of blue powder to mg 2) Convert the volume of H 2 O in the Erlenmeyer flask to liters (L). 3) Convert the width of the table to kilometers.
