Find the amount of O2 the blood absorbs in the lung in a minute

    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.
    Here's what I did
    100ml blood -> 14 ml O2

    70 ml blood -> x

    x=0.98 ml O2

    The heart beats 70 times
    So 0.98*70=68.6 ml.
    Is this solution right?

    If you were trying to solve the proportion problem

    ##\frac{14\, ml\, O_2}{100\, ml\, blood} = \frac{x\, ml\, O_2}{70\, ml\, blood}##

    You might want to check your calculation of x again.
