Calculate the molality and mole fraction of 5.0g of ethanoic acid in 150 g of benzene​

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?

Can someone me with 6 to 10 plz this is for masteries test.

All forces cause motion? true or false
