How many grams of nitrogen dioxide are in 1.28 x 10^23 molecules of nitrogen dioxide (NO2)?
A. 9.78g of NO2
B. 9.78 moles of NO2
C. 9.78 x 10^23
D. 9.78 g x10^23

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
