Chem 171 Quiz 2 Version A 1. Is density an extensive or intensive property? Why? What is the SI unit for density? Density is an intensive property. Density is mass / volume. Both mass and volume are extensive properties but the quotient is an intensive property. Density is independent of the amount of substance. The SI unit for density is kg/m 3 . 2. The following “fill in the blanks” refer to the lab entitled “NET IONIC EQUATIONS”. When metal and non-metal atoms join, they usually form an ionic compound. Metal atoms usually form cations. Non-metals tend to form anions . The force holding an ionic compound together is electrostatic attraction. The force holding an ionic compound together is governed by Coulomb’s Law. Chem 171 Quiz 2 Version B 1. An Olympic size pool is 50.0 m long and 25.0 m wide . How many liters of water (d=1.0 g/ mL) are needed to fill the pool to an average depth of 4.8 ft? 1 ft = 12 in. 1 in = 2.54 cm. 1.057 qt / 1 gal. 1 gal = 4 qt. V = abc What is the mass of the water in the pool in kg? Depth in m = 4.8 ft x 12 in / ft x 2.54 cm / in = 146 cm
