How many moles of \rm CaC_2O_4 are present in this kidney stone?

Answer 1

The equilibrium constant, Kc, for the following system is 24.4.
H2(g) + X2(g) 2 HX(g)

At equilibrium, a system contains 0.200 moles of X2 and 0.600 moles of HX in a 4 × 10–3 m3 container. Calculate the number of moles of H2(g) present at equilibrium.

Select one:

a. 0.059 mol

b. 0.074 mol

c. 0.0123 mol

d. 0.295 mol
