If the mass of an unknown object is 2 grams and the volume is 2.35 cubic centimeters, what is the density of that object? a.

b. Look back at Table 4.1. Based on your calculated density, what is the substance?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
