65 mg/ml what is the appropiate volume to adminster to a 300g rat at a dose of 40 mg/kg?

Answer 1

looks pretty simple

40mg / kg
but we only have 0.3 kg, so we need 0.3*40 mg
or 12mg

The solution contains 65mg per milli Litre
we only want 12 so that's 1 milli litre *12 / 65
= 0.185 ml (0.185 cc)
