Can someone work this out

Hi, I need some urgent help with this drug calculation.

You are required to give 300 micrograms of drug x. The ampoule contains 1:5000 solution in 5 ml. How much are you going to give?

1:5000 = 1 gram in 5000mls. I'm not sure what the formula is.

It would be great if someone could show me step for step.:)

thats really confusioning. the way i see that, is that there is 1 gram in 5000mLs, or 1gram in 5 litres. so that would be 20mg in 1 litre. convert that to micrograms, and thats 20,000 mcg in 1000mls. so thats 20mcg in 1mL.
so if u wanted to give 300mcg, you would give 15mLs.

im not sure if thats correct, but thats what ive come up with.

Thanks for your suggestion. How do you get 20mgs? Would you convert the micrograms to grams?

Change 300mcg to grams-How would you do that.
or
Would you change grams to micrograms?

1 gram in 5000 ml =
1000 mg in 5000 ml=
1 mg in 5 ml=
1000 mcg in 5 ml
To give 300 mcg, give 0.3 X 5 = 1.5 ml
A very bizarre calculation question.
