A liquid has a specific gravity of 0.50. What is its density in g/cm3 ? What is its specific volume in cm3 /g? What is its density in lbm/ft3? What is the mass of 3.0 cm3 of this liquid? What volume is occupied by 18 g?

Chem 112 9-7-16 What we have so far Reaction with reactant coefficients α and ß αA + ßB = γC + δD Overall rate expression: Rate = -ΔA/αΔt = -ΔB/ßΔt Rate laws relate exponents to orders of elementary reactions that are part of mechanisms o Not necessarily observable or able to be directly measured Rate = k[A]x[B]y Key: combine this knowledge to experimentally validate this proof Acquiring useful experimental data Method of initial rates o Why Reactants decrease over time, products increase A+B Products Vary [A]o and [B]o – keep one constant, vary the other, then vice
