B) calculate the number of moles of hydrogen iodide that have been made after 5 minutes.
please help me

    ............H2 + I2 ==> 2HI
    I...........1.2..1.0......0
    C...........-x.....-x.....2x
    E................0.6........

    I2 reacted must be 1.0-x = 0.6 and solve for x.
    Then E for H2 must be 1.2-x = ?
    Then HI must be 2x.
