Dosage Calculation PLEASE HELP

Can someone please explain to me how to set this problem up?

4g of Magnesium Sulfide in 250 cc of D5W has been ordered for IV infusion at a rate of 34mg/min. At how many microdrops/min should you infuse the IV using a solution administration set that delivers 60 microdrops/cc?

    Here's how I think it is set up. Someone correct me if I am wrong:

    250 cc/4G x 1G/1000 mg x 34 mg/1 min x 60 gtts/1 cc

    cc, G, and mg cancel out, leaving you with 12.75 gtts/min.

    Is that right? Anyone?

    You have it set up the same as me, but I got 128 gtt/min.

    you're right! I am using this awkward calculator on the computer, and must have missed the decimal somehow... that's a med error;)
