### Help! Convert mg/ml to mg/kg

Okay, I have nitroglycerin at 5mg/ml (in liquid form).

My mice need a dose of 10mg/kg.

I have 8 mice weighing approximately 30g.

How do I figure out how to dilute to the proper concentration and volume?

I think I need to use C1V1=C2V2, but I don't know how to get the end result.

PLEASE HELP!!!

You do not need C1V1=C2V2.

Your mice need 10 mg/kg and weight 0.03 kg, calculate X (in mg) the total amount to inject.

You have a 5 mg/ml solution divide x by 5 and you know Y the number of ml you need to inject.

With a C2 of 1mg/ml, and If I am injecting .3ml for a .03kg mouse, then how did I get to this point?

So....

For 8 mice weighing approx 30g each (+a little extra just in case) I was given this information.

C1= 5mg/ml

V1= .8ml

C2= 1mg/ml

V2=4

I need to add saline to the nitroglycerin to get the proper concentration, dose and volume. I'm lost...

OK the complete solution for a 30g mouse you need

0.03kg x 10 mg/kg = 0.3mg per mouse

so with your initial solution you are suppose to inject 0.06ml or 60µl.

If you prepare a 1mg/ml solution, 300µl are necessary

0.03kg x 10 mg/kg = 0.3mg per mouse

so with your initial solution you are suppose to inject 0.06ml or 60µl.

If you prepare a 1mg/ml solution, 300µl are necessary

One last question. How would I prepare the 1mg/ml solution with the original concentration that i have which is 5mg/ml nitrolgycerin?

and I also understand how you got to .3mg per mouse, but how did you convert that to 300microliters per mouse? Because that makes sense, we inject .3ml for a 30g mouse.

Thanks you again, i dont know why i cant wrap my head around this

1/ dilute 5 times, or in this case use the c1v1=c2v2

2/ 1mg/ml means that you have 1mg of product in 1ml of solution. if you want 0.3 mg of product, how much solution?

PS: brain usage is not optional.
