Respiratory system help needed

    1. The problem statement, all variables and given/known data
    Hi everyone, ive been doing this question and im now stuck on part b as i dont know how to find the anatomiclal dead space volume.....can someone help me out please, ive thrown in what i have done so far

    thanks

    Clemy is taking 14 breaths per minute. Her vital capacity is 3,000ls, her total lung capacity is 4,000mLs, and her tidal volume is 450mls per breath. Calculate the following:

    2. Relevant equations

    Alveolar ventilation = ventilation rate (breaths per minute) x (tidal volume – anatomical dead space volume)

    3. The attempt at a solution
    (a) Clemy's total pulmonary ventilation (minute volume)
    Total pulmonary Ventilation (Respiratory Minute Volume) = volume of air moved each minute
    Respiratory minute volume = ventilation rate (breaths per minute) x tidal volume.
    Respiratory minute volume = 14 x 450
     Respiratory minute volume = 6300ml per minute = 6.3L per minute

    (b) Clemy's alveolar ventilation rate

    Alveolar ventilation = 14 x (450 -
