Answer #1

The question is incomplet, it must have value of Kc

        A(aq) ------ 3B(aq)

Initial    2M            0

Final    (2-x)M       3x

Kc = [B]^3/[A]

Kc = 27x^3/(2-x)

substitute the value of Kc and solve the equation for x, to get the concentration of B just mutiply the value of x by 3

If you are available, then just comment the value of Kc, i will solve the problem completely
