Question

1. what amount of solute present in each of the following solutions?
(a) 750 ml of 2.00 M HNO3 (1.50 moles, 94.5g)

Answer 1

6. Determine Keq for the reaction: 2 SO2 (g) + O2(g) 2 SO3(g), given that 1.00 x 10-2 moles of SO2 and 2.00 x 10-2 moles of O2 were placed in a 2.00L reaction chamber. The chamber contained 7.5 x 10-3 moles of SO3 when equilibrium was established at 727oC.
