I need help with this question What is the percent by mass of oxygen in sugar? Of carbon? Of hydrogen?​

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?

Label a-f based on the table using c for concentrated and d for dilute
