For the masses and volumes indicated, calculate the density in grains per cubic centimeter. mass = 452.1 g: volume = 292 cm3 mass = 0.14 lb: Volume 125 mL mass = 1.01 kg; volume = 1000 cm3 mass = 225 mg: volume = 2.51 mL

For these questions, be sure to apply the rules for significant figures. a You are conducting an experiment where you need the volume of a box; you take the length, height, and width measurements and then multiply the values together to find the volume. You report the volume of the box as 0.310 m1. If two of your measurements were 0.7120 m and 0.52145 m, what was the other measurement? b If you were to add the two measurements from the first part of the problem to a third length measurement with the reported result of 1.509 m, what was the value of the third measurement?

Multiply or divide the following measurements. Be sure each answer you enter contains the correct number of significant digits.
