    1. The problem statement, all variables and given/known data
    100 ml blood of lung vein contains 14 ml O2. The volume of blood in the left ventricle is 70 ml. Find the amount of O2 the blood absorbs in the lung for a minute.
    2. Relevant equations
    100ml blood -> 14 ml O2
    70 ml blood -> x
    3. The attempt at a solution
    Here's what I did
    100ml blood -> 14 ml O2
    70 ml blood -> x
    x=9.8 ml O2
    The heart beats 70 times
    So 9.8*70=686 ml.

    Looks good. That is, you omitted a decimal point in one of the numbers, but it s obvious it just a typo.
