Need Help with this drug calculation

Hello,
I'm a med/surg nurse who needs a little help with this math problem.
I am trying to refresh my math skills that I haven't used in a long time. The problem is a procainamide drip is ordered for 2mg/min. the standard mixture is 2g in 500 ml. What should the iv pump be set for ml/hr? I need a formula or something. Thanks

This is the way I make sense of figuring these calculations. I know there is a more appropriate way, but I get to the same number.

Since there are 2mg in each 0.5mL, the flow rate should be 0.5mL/min.
and 60 minutes x 0.5mL/minute = 30 mL/hour.
As a check, 30 mL/hr x 2mg/0.5mL=120 mg/hr. Also 2 mg/min x 60 min = 120 mg/hr.

2mg x 500ml x 60min x __1 g__ = 30ml/hr
min 2 g 1 hr 1000mg
That's the way I would set it up....:thnkg:
