1. A teacher instructs her students to measure out 50.0 mL of hydrogen peroxide for three trials of an experiment. A student measures out 37.2 ml, 38.7 mL, and 36.9 mL. Use this information to answer the questions below (1a and 1b). 1a

Calculate the percent error for each measurement and include them below. (For example: 1%, 2%, 3%)

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

yes the answer is total mass in unchanged   : )
