The physician has prescribed a medication of 3.5 mg/kg of body weight. If you give 297 mg of medication what is body weight of patient in kg? Is there a converstion formula?

    I don't know that there is but you can make one.
    3.5 mg/kg x # kg = 297 mg.
    Solve for # kg.

  • chemistry -

    Tell me what you think: I wrote
    #kg = 297mg / 3.5 mg/kg the mg's would eliminate each other and you are left with 297 / 3.5 kg = 85 kg.

  • chemistry -

    Your answer is correct; however, you haven't made a new formula. You've just solved the equation I gave you.

  • chemistry -

    that is very true. What I was asking involves something like this as an example:

    30mg/kg*1000g / 1kg* 1g /1000mg
    30-/kg* 1000-/1-* 1g/1000-
    30 * 1000/1000 * 1g = 30g

  • chemistry -

    You might be thinking of something like this in dimensional analysis. The factor is 3.5 mg/kg (or 1 kg/3.5 mg).
    297 x (1 kg/3.5 mg) = 297/3.5 = 85 kg.

    Thanks, That's it!
