how do you do this please explain steps

First, we should find how many mg we need for the mouse. We do this using our dose of 2mg/kg and our mouse’s bodyweight of 23g. We need to make sure our units are the same, so we can use 23x10-3kg for the mouse’s weight. Multiply the dose with the weight for total mg.

Now that we have total mg, we need to calculate what volume of the antibody we need. We do this by dividing the total mg by the concentration.

Hopefully this helps you follow it through - have a go and see what you get!

Thanks so much

A dose in mg/kg reflects how many mg of drug is given per killgram of bodyweight. This is often how drugs are given so that animals/people of different sizes are receiving the same dose, with a different total mg reflecting a different total amount of body tissue. So for example a 1kg rabbit would receive 2mg of antibody but a 5kg dog would receive 10mg, both at 2mg/kg.

I’m not sure I’ve explained that the best but hopefully it helps?

Hi ! I would also want to ask why divide the mass of the antibody by 500 which is the concentration, how does it give you the dm3 needed ?

Because:
1/dm-3 = dm3

Hi that still confuses me can you further explain? What is the reasoning for making it into dm3?
